I thought this was pretty cool. I got this program called last.fm where you can type in an artist or a genre and listen to songs without downloading kinda like a radio. Instead with this program you can skip songs and search for songs.
     What I really liked about this program is that when I listen to music on itunes, and quiote possibly any other type of application that plays music, it will stalk the program and recorded what I listen to. Then this is posted on my profile here.
