Hanging out at a friend's house last night and realized that he was using YouTube as his music jukebox. I thought it was strange until I realized that it's actually a really good alternative for people who don't want to invest in building their iTunes library. The downside is that after each song you have to search for a new one ... but we had fun hanging out and making suggestions [and I learned that my wife is currently obsessed with Cold War Kids - see video below].
