A whole new genre of YouTube videos?

On an assignment for Library School, I happened across a YouTube video of a record spinning Van Morrison's Redwood. It turns out, there is not only one channel devoted to this kind of video, but actually quite a few, and some with specialities, like 78s or colored vinyl and picture discs. The variety of record players and turntables is fun to check out as well. How am I supposed to do homework now?
