Taking a look at Swisscows right now. My only concern with them is that I know they filter out sites with adult content, and I do have worries on how that’s applied to results with explicit song lyrics or album covers.

I gave this a shot since I do like and trust Mojeek, but unfortunately it doesn’t appear to bring in any results when I use the search “site:bandcamp.com attribution non-commercial share alike” (not in quotes).
