I often use Yahoo's Launchcast to listen to streaming music at work. Usually it's pretty cool, even though I use the free -- and advertisement-laden -- version.
Unfortunately, it appears that Green Day will be here in Atlanta in concert next week. Why is this unfortunate? Because after every 2-3 songs, I get treated to the beginning of "American Idiot" and the same minute-long commercial for the concert. It has the potential to drive one insane from the repetition. I don't know, but I think I'm cracking up.
But, I guess I get what I pay for.
