You definitively should do that, but I doubt that it will prevent your data from being trained on. It sucks, but that's the reality now. I stopped using Spotify a while ago. Never using it again for sure.
Won't stop the scraping, but the terms go way beyond AI training. They more or less retroactively changed the ToS to revoke all your IP rights to a work.

I don't know how much of it is enforceable in court, but I wouldn't want to take that risk if I hosted anything as an indie.
What's your alternative? I enthusiastically do not care for podcasts, news and social "features". Recommendation for a just (all the) music, no shenanigans type of service?
Tidal is a pretty good general music app as a Spotify alternative and reportedly pays artists a lot more for plays.
I also fairly liked Qobuz, a French service, but ended up dropping it because it didn't have the kind of "just play something I like" feature that Spotify and Tidal have made pretty standard now (daily mixes, etc). I hate the laziness of it but I've gotten used to it; there are days/times I just want to listen to music of a certain mood while I'm working on something and don't want to think hard about what to put on.
I switched from Spotify to Apple Music last year and as far as I know, there are no podcasts, news, or social features. If those things exist, they aren't in your face like Spotify. The library seems to be similar.
Actually, because you can play radio stations and some radio stations play news, news is on there.
That's what I use. YouTube on a free account is unusable, and I don't trust ad blockers. YouTube Music isn't perfect. A lot of songs aren't there or it's a music video version, but there's things like concerts, compilations, session recordings, covers, people improvising, etc.
