I was looking at Macrumors and thier post about dailytunes.comS which basicaly functions as a site that recommends music that you can buy from the itunes store. One of the bands they recommend is The Post Service, which is on the Subpop label. It is in fact on the itunes catalog along with Mudhoney, but the rest of Subpops catalog of bands is absent.??
