I am not sure what you mean here. I just checked my uploads and all my live music stuff is still there, as well as obscure published records.
I don't care that nobody else on YouTube would ever have wanted to hear them. I don't even really care that the band members themselves would probably be embarrassed that I still had a copy. The point of buying the disk (and uploading it in the first place) was so that I word continue to have access to it.
