I've noticed that on the music channels I listen to I know every song played. There was a time (pre-merger) where I would hear songs by known artists that I have never heard before. It seem now that Sirius has forced their hits only top 40 programming on XM. What Sirius calls obscure music is one of the things that brought me over to XM from Sirius. I KNEW Sirius was gonna' fuck up XMs' playlists post merger.
