I'm with you there all the way!
I always thought that the music in the menus was elevator music or boring jazz music that you listen to in real life car dealerships espically luxury car dealers,

, but my parents think otherwise about it, espically my mom she say it much more calm than what I listen to

(rap, metal, alternative, techno & electro when it comes to cars and music

not elvator/jazz

). I follow The Fast and The Furious & Need For Speed(from NFS II to Carbon) theroy.
Techno/Electro: Tuners, Euro Tuners, Sportbikes, Exotics(older NFS games)
Metal/Alternative: Muscle, Aussie Muscle, Sport Trucks
Rap/Hip Hop: Exotics, Luxury Cars, Luxury SUVs
Or all music with all the cars, which is better.
That's why I have a iPod for

! But the music on GT5 somehow is growing on me.
