I have mentioned this album to several people, but it bears repeating. In fact, it bears writing about it a little. "Feed the Animals" by Girl Talk is a tremendous album that comes on like the final exam for a Master Class in pop music. It contains bits and pieces of hundreds of songs put together like a whole new language. Some people ahve dismissed it as a set of DJ tracks or remixes, but that is a gross misunderstanding of the encyclopedic knowledge of music and skill required to create this album. Imagine taking the all the songs you know and, instead of mixing those songs together in a giant crossfading mixtape, taking just the best parts of those songs and matching the beats and keys of each little part while layering them on top of each other to create a new song.
I challenge you to listen to it and write down the songs you think you hear. Then go to this list and check your work. The crazy part is that the list is not comprehensive.
Oh, and it'll make your head move in the car, your rump shake in the kitchen, and your toes tap in the office. Provided you have headphones on, because there is a fair amount of expletives heavily seasoned throughout.
