It would appear that TheCoolTV has been trying to become the new Vh1 Classic. They played Holiday videos from 6 pm on 12/24 through 6 pm on 12/25. And right now, they're doing a year-end A to Z countdown, which started yesterday afternoon at 2 pm, and will run through midnight on New Year's Eve. I remember Vh1 Classic did a very similar thing a few years ago called "2009 for 2009," except it started at midnight on New Year's Eve, and lasted for 7 days. But they went in order by song titles, and this one is going in order by artists, and I think it's just one song per artist.
In general, it would actually appear that Vh1 Classic has been phasing out airing music videos. Until a few months ago, they did have a block of random videos every morning from 6 am to 9 am, but it has been replaced with their usual rock docs or whatever they're called, and they now air classic Pop-up Video episodes, presumably to coincide with the regular Vh1's revival of the series. Vh1 Classic still airs Rock Fest, Totally 80s, and Metal Mania. TheCoolTV has very similar blocks of programming, such as the 80s at Eight. I think TheCoolTV is better for music videos, but there is no format at all, and they play a lot of music that I don't think anyone has ever heard before.
