Im having the same problem!
i did find out though, how to play the songs on the music player.
Go to the "Documents" app and then pick "Memory Card" then chose whatever folder you saved the music files on, then click "Options" and the n click "Play".
there is a problem though, only one song will appear to be on the playlist, so u are going to have to go back into the folder and click on another file in order to ,listen to it.
