One new fangled phenomenon that I have yet to get on board is music mashups. I've seen them referred to many times and there are even some pairings that sound incredibly intriguing to me (The Beatles and The Beastie Boys, anyone?), but I've yet to listen to one.
But when Boing Boing provided a link to, of all things, a mashup of Beyonce and the theme from the Andy Griffin Show, I clicked on it. Ooooh, boy will that stick in your head. Have a listen.
