They do nothing. That television channel only shows videos:
-from 4am-5am (or some ungodly hours like that)
-on TRL in which they only play the first 30 seconds of the videos.
They say that if you want music to watch MTV2 or MTV Hits or MTV Tres' or MTV Jams... but all they play is rap. And that's fine, in the sense that that's what's popular right now (even if musical tastes are suffering and dying). But I've turned my attention to FUSE. That's a far better network is besides Pants off Dance off, they actually play music and full videos by some more obscure bands. I also watch VH1 a lot.
But I can't pull myself away from the retardo dating shows on MTV. I was watching NEXT this morning because I feel so smart when I watch those idiots.
