okay the other day i was playing some music as normal and clicked to play another song that ive played many times before and nothing would play, it shows in the bottom right that it is but no music? music on myspace works or when i put cds in, but even now the music that i had saved from cds in my music folder wont play either! i tried uninstalling, restarting pc, virus scan, adaware scan, re dling songs, idk??!?!?!?!?!?

Which audio format is it?
