Agree that VH1 is a mess and mostly a clone of E! and MTV...
Though I sometimes watch "I Love the __" and cheesy countdowns ("100 Songs of the ___") for archival footage that they would show.

VH1 Classic is slightly better (for now), though mostly focus on classic rock, movies (especially that have nothing to do with music

), rejected VH1 specials from the past several years, and music videos during the night... though they tend to be very repetitive and very selective (ie only a few videos from artists).
(I have nothing against classic rock, but I like more variety and also more shows/specials from the Viacom vaults)
