Is The List I Have Compiled Considered A List Of Lost Music

Where on the site would be the best place to post it?

I was able to find some of these on the music sharing community Soulseek, so I can actually download them and put them up YouTube, but currently none of these are on there. This also is not everything, the one I keep personal is not completely organized, as you can tell some of them have the album edition they are from and some don't
