Believe me DJ Perry, you are definitely NOT the only one pissed. Let's also add "The Move", "The System" and "Chrome" on XM's side as well.
You now have NO dedicated classic dance outlet since "The Strobe" and "Chrome" are both gone (they're telling people to go to 70's on 7 and 80's on 8) and that has fans of that music in a frenzy. We're kinda lucky in New York City that there are 3 area stations that do classics, but for that poor person outside of the region, they now have nothing.
Boombox had a core audience for those that liked the mashup/electronica side of dance. While "The Move" hadn't been on XM receivers for a bit, there was still an audience that loved the deep house music, to which "Area", while a great station in itself, doesn't touch as much on deep house in the way that "The Move" presented itself.
BPM replaced "The Beat" so to speak but even there you have an argument since "The Beat" was for the casual, non-core, pop-remix fan versus BPM, while fine for core fans, could come off as rather "intimidating" for those used to "The Beat. And yeah, I'm noticing BPM to be somewhat "watered", though still a good station.
Though I am not much of a hip-hop fan, I am shocked about "Throwback" being dumped. I would think eventually more terrestrial stations (like the dance station we lost in Phoenix) would flip to an old skool format, figuring it targets the older audience that liked the music from the late 70's to early 90's.
People have been telling me they have cancelled their subscriptions because of the merger. Not good when you consider the 16 rock stations, some of which are artist specific.
