I suggest loading them to Youtube. People don't always know if their computer is infected (and often think it isn't) and download files are thigns some people, such as myself, skip.
Plus, if the music has been subitted for copyright purposes to Youtube, if any music you upload trips the copyright, it'll tell you what it is. Pretty handy, huh? ;-)
I've used Youtube's copyright system to identify music before. doesn't always happen over night, mind you.
