CAN YOU DOWNLOAD MUSIC ONTO A PS3?

Yes. The PS3 will play and copy/rip MP3, WMA, and AAC audio files. And, of course, the traditional WAV/CDA that is the file format of your ordinary audio CD. It imports tracks from audio CDs; go to the Music Settings first and choose what format & bitrate you want the music to be converted to. MP3, WMA, and AAC files on a data disc or USB drive are merely copied; bitrate, tag info, and file format remain the same.

The PS3 is capable of playing your music during games, but Sony does not mandate it like Microsoft does, so its up to the developers to implement the feature into their games and only a handful of games support the feature. Here is a list some of the good folks at the Playstation forums are trying to create:

you can just download the music into a thumbdrive or something like it and transfer it onto your ps3 however you cannot listen to music and game at the same time
