Okay, I tried emailing thia question but got no reply so I'll try here.
I've put out a fair amount of music under the name Doctor Turtle, which has varying flavours of Creative Commons licenses (mostly BY-NC-SA and BY 4.0). It's been reasonably successful on the Free Music Archive, and occasionally people ask me why it's not on Spotify. The reason so far is, I don't know how putting it up here will affect the people who've used it in their Youtube videos, and I don't want to risk them getting takedown notices through the content recognition service.
So, if I put it up here through an aggregator, how do I make absolutely sure that doesn't happen? I can't afford to get it wrong, as quite a lot of people have used it, and it would be a breach of faith for them to end up having their stuff removed.
TIA to anyone who can help with this. Doc T
