Yes, Discogs is basically the IMDb of musical recordings. Its marketplace is probably the best place on the internet to find and sell physical copies of pretty much any musical recording.

They don't sell or host digital recordings, presumably for copyright reasons.

Shame, I've been wanting to buy a Wendy Carlos digital album for ages. Guess I'll have to keep wishing. sigh

I realize this is probably not a great consolation, but you could buy a CD for just a few bucks and rip it yourself.

Looks like it :-/ was hoping I could find digital recordings.
