I got an email from Game Stop today containing a new advertisement for GT5 Prologue. It seems to mention the inclusion of custom soundtracks in addition to the regular soundtrack with the exclusive Weezer song. The custom soundtrack feature is something I've been hoping PD would finally include, since I had PGR2 on the original XBOX. I'd really like to play my own music off the hard drive while playing GT5 Prologue, especially when doing races repeatedly to earn credits, etc. This is the first mention of custom soundtracks I've personally seen. Anyone else heard anything about this?
