I have fallen in love with mashups. They are just the coolest thing since .mp3 in my not so humble opinion. There have been a few famous ones, such as DJ Dangermouse’ Grey Album, but my favourite thus far is by DJ Earworm called No One Takes Your Freedom. It’s a mashup of Scissor Sisters, the Beatles, George Michael and Aretha Franklin, and it works amazingly well. Check it out here: Link
This is the kind of excellence that happens when you have free access to create new works based on older ones.
