This is how to get free music, but you need to have a windows xp and windows movie maker.
Step 1: Change input
Change audio input to "stereo mix"
Step 2: Site
Go to a site where it will play your song that you want (videocodezone.com)(youtube.com)(google video)
Step 3: Wrapping it up
go to windows movie maker and hit "start narration" and then quick go to your site and click play. when the song is done, click stop narraration and then save the song. this is a wma (windows media audio file) so most mp3 players (even the cheap ones like mine) will be able put the song on your mp3 players. i HAVENT tested with IPOD.
