Those that did, how true is this music to the original channel's music?
according to the website they played a lot of jazz and instrumental stuff, but I was surprised to see songs by The Smiths, The B-52s, Moby, Smashing Pumpkins, Aphex Twin, R.E.M., Sublime, James Blunt, and Pink Floyd. They must have had a decent budget to license those.
