Don't get me wrong the soundtrack for Burnout Paradise is pretty great, but there are only so many times you can listen to "Girlfriend". I heard there was a way to import your own music, but I don't know how.
PS3 version by the way.

Here's a video from criterion how to do custom soundtracks link

It's in an update, so make sure your game is updated. I'm pretty sure it's found by pressing Right on the D-Pad, then you should be able to scroll down to "Soundtrack." It's been a while since I've seen the PS3 version, so sorry if some of that info is incorrect. But yes, you can absolutely use you own music. :)

Ha, yeah took me awhile to figure out too.

Yeah, I probably enjoyed the soundtrack of that game more than most but the custom soundtrack is a very nice feature.

Just done this, now I can go really fast with some Glee!
