In ATV Offroad Fury: Blazin' Trails for the psp, how do I get music on it so I can listen to it while racing?

[Mad Dog <tiger_cat_2713>]

I have the music already on my psp, the files are mp3, ARE THERE ANY SPECIFIC FILE TYPES THAT IT HAS TO BE CHANGED TO (how would I do that), AND HOW EXACTLY DO I TRANSFER THE MUSIC? I want to listen to my Nickelback music so much, yet cannot enjoy it while racing
Then what is the scan option for under the 'Jukebox' menu for?

Well, you can't play games and play music at the same time. You have to do them separately.
