Well, as per the question OP poses, allow me to answer it. I have eleven of them, all of which I alternate between.
Space 103.2 - With your host: Bootsy Collins, baby! Now say it with me, bobbas...”Funk is making something out of nothing.” I find it hard to NOT groove to this collection of funk classics whenever I’m driving my crimson Elegy RH8.
West Coast Classics - The classic hip-hop station, featuring some of rap’s finest...up to the year 2000. It’s run by DJ Pooh, who co-wrote GTA Online and GTA:SA - outside of R*, he played Red in Friday, and gave us The Doggfather, which went double platinum...and that’s only one of countless albums he’s produced over a career that spans three-plus decades. So it makes sense to have him head up of radio station composed of late 20th-century rap and hip hop that he picked himself. I’m not a fan of all of the songs on this station, but that statement is proof that no era of music was 100% perfect (and sadly, that statement could not be more true in the 2017 we live in). At least Bone Thugs-N-Harmony, N.W.A., Dr. Dre and Snoop Dogg - all of which I really like when they’re on top of their game, but appear to be past their prime/disbanded - are on this station.
Rebel Radio - Get out the moonshine and pull up a seat next to Jesco White if you plan on roaming Blaine County. For me, this is what country music is supposed to sound like. In other words, it’s country music before it became white guys with cowboy hats and Southern accents singing about the same things you would hear out of a rap song. Also, Johnny Cash. Shame his cover of "Hurt" didn't make it into the game instead of a song that I firmly believe, based on its title, he wrote and performed because some TV executives wanted him to write a song for their new show, "The Dukes of Hazzard".
Los Santos Rock Radio - Beautiful classic rock and power pop station, hosted by none other than Kenny Loggins - if you were to ask me, I'd tell you that he's the perfect host for this kind of radio station. He seems to remind you that you never know how much time you have left, and to make as much of it as you can before you pass on. And this wonderful collection of classic rock from the 70s and 80s (this isn't me advertising anything, I really do love this station) As far as my top 10 picks for my favorite songs out of the entire soundtrack, I’d definitely place “Cat’s in the Cradle” in the top 5, but not at #1. “Carry On Wayward Son”, the prog rock classic by Kansas, is my favorite song from this radio station, but it’s also my second-favorite song from all the radio stations.
The Lowdown 91.1 - I'll admit that I have a soft spot for old-school R&B and soul, although I barely know any notable performers from that era. This station, headed by Pam “Mama G” Grier, takes you on a trip into the wayback machine (no, not that one) and looks at the work of those that helped to define R&B, at it's most intelligent and sophisticated. But what it brings to this meeting is that unique flavor that only early R&B and soul could be known for. Seeing as it was mostly sung/performed by black people, it could also be considered a major ancestor of hip-hop as we know it today. Many, if not all of the songs, could easily be sampled in a rap song that sounds like it was produced in the late 80s or early 90s. If I ever need a break from today’s era of music, I’ll throw this station on to get an idea of what people were listening to in the early 70s, before computers made music what it is today.
P.S. “Across 110th Street” by the late, great Bobby Womack would make a great fit on this station. Seriously, listen to it.
Non-Stop-Pop FM - The way we know pop music now, how it’s almost-all digitally produced nowadays - to be fair, it was always like that but never as much as it is today, I need something to take me back into the annals of time and remind me of the pop music of days gone by. Cara Delevingne - a model and socialite who was born 8 1/2 months before I was - is here to do that for me. This playlist, made of pop giants of the past and present like Lady Gaga, Rihanna, INXS, Wham! (RIP George Michael, 1963-2016), Pet Shop Boys, Lorde, Maroon 5, M83, and pre-“ok let’s start recycling The Time (Dirty Bit)”-era will-i-am (as part of the not-quite-disbanded Black Eyed Peas), reminds me of how mostly amazing pop music can be...and in many cases, has been.
Sadly, those last two words can be used to describe at least half of the acts on this station...if they're still around, that is.
Worldwide FM and FlyLo FM - Anyone who’s at heard of French-born record collector Gilles Peterson, either through his radio show Worldwide, listening to BBC Radio 6 Music on a Saturday afternoon, or his Soundcloud page will probably end up being with some of the works he’s playing here. It may not be stereotypically classified as dance music, as there’s no electronic beat backing most of the music he plays. Or, if it is electronic, it’s usually not the straight four-on-the-floor beat that EDM is familiar with. Then there’s experimental hip hop musician Flying Lotus, who’s produced most of the bumper music you may have heard on [adult swim]. From what I hear, his music gives off the feeling that you would expect from a fine wine. Also, he gets a plus for collaborating with Kendrick Lamar. Neither of them play beats that you would expect to hear out of their genres. Or in other words, popular. But as long as it’s something to get the party going, they’ll play it. To me, that is what ultimately makes both stations worth listening to, along with WorldWide FM for GP’s life-long devotion to the music industry, and FlyLo FM for the occasionally funny jokes that ultimately get repetitive after listening to this station for too long.
Radio Mirror Park - I had no idea I would like this independent synth pop station, hosted by George Lewis Jr./Twin Shadow. This is one of the cheesiest radio stations I’ve ever listened to, but I can sit here and type out the words "I ENJOY THIS STATION MORE THAN I SHOULD!". That doesn’t mean I listen to it all the time, though. I listen to it in quick bursts if I need to hear some throwbacks to what I loved about 80s synthpop like “Chains of Love” or any of the 80s synthpop on Non-Stop-Pop.
P.S. Even though it was one of the biggest hits of 2015 and I think it might be DQ’d because of this, do you think “Style” by Taylor Swift would fit in here? I don’t know, but to me, it seems like it’s “too good” for Non-Stop-Pop.
The Lab - I understand that this is an entire album produced by the two people that host this station - both of whom worked on the score. It spans four or five genres of music, and manages to do all of them justice. Among my favorite picks, there’s “Wanderer” by Little Dragon, “Play It Cool” which features some of the best rapping I’ve heard in the last five years, “Leave” by Wavves which is a rearrangement of the music heard in Complications - just with Nate, Steve, Alex & Brian this time, and the unofficial theme song of the fastest of all racers in GTAO any multiplayer/PvP racing game in “Speedline Miracle Masterpiece”...which also happens to be my favorite song. Not from this radio station, but from all of the radio stations in the next-gen release of Grand Theft Auto V, period. I just love every second of it - the synth-blasted intro, the wordplay, the beat, the atmosphere; it makes you feel like you’re a professionally-trained street racer; you go so fast compared to everyone else, leaving almost all who stand before you looking at your taillights as you speed off into the distance*. I listen to it in full whenever it comes on.
*This statement sums up most of the public race lobbies I’ve been in over the past month.
Self Radio (I know it’s not listed here AND I’m on PS4 instead of PC, but I’m putting it here anyway) - For a PS4 player, I guess the Media Player is the best alternative if you want to select the music yourself and put it on shuffle. Downside is that you don’t get to listen to the banter of the DJs/news/commercials in between songs. I can’t say anything more about this station, except that you could have some fun, 🤬 with your own musical sensibilities and throw on "Snow Halation" if you’re feeling blue...better yet, play it over your headset and see what kind of reaction you get.
P.S. I'm dead serious, try it yourself and see what happens. IMO, Snow Halation is an even better song than Speedline Miracle Masterpiece.
...and that’s all I’ve got. Welcome to Los Santos, indeed.
