sitting here wiggling around in my chair to kanye's workout plan...but if you checked my itunes, you'd find that i was just listening to no cars go by the arcade fire, nth degree by morningwood, don't you worry about a thing by john legend, and electric by tristan prettyman. these songs have NOTHING in the way of commonalities. it's too bad that there isn't some sort of product that will break down and analyze the rhythms, instrumentation, and lyrics of your favorite songs, come up with some common denominators, and be able to recommend new music for you...
