Guess no one else noticed this. I checked those two channels Saturday afternoon to see what they were up to, and heard loops saying they would no longer be available. I guess MTV channel 155 is being replaced this Monday with the new Take 5 channel. I had also notced that Discovery Channel Radio had disappeared in recent weeks and figured Take 5 was replacing it. This is a little sad, because even with minimal commercial interruptions, MTV and VH1 were still good alternatives to XM's other hit music channels (KISS, MIX, and 20 on 20) which have no jocks at present. Any possibility they would take some of the jocks from MTV and VH1 and move them to Kiss and Mix, and maybe 20 on 20? If so, it wouldn't be a bad trade off, and would actually make those channels better.
