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).

Honestly depends, but if you want an all-around good instance on a misskey fork, try lethallava.land

Honestly Misskey forks for all their flaws can absolutely take this opportunity to properly advertise themselves as viable alternatives. As someone who uses a Misskey fork, I love the UI in comparison to Mastodon, and the communities in Misskey forks are a lot less techie and a lot more laid back and goofy most of the time from my personal experience.
