You can rip them from tidal quite easily. Youtube also has lots of music to rip but in shitty quality. That being said, music piracy has declined quite a bit since spotify. I'd suggest getting into a private music tracker if you really want to.

wrote a python tool to do daily scrapes from a russian music tracker site and sync all the titles onto a mariadb database. led me to discover all sorts of music which I would otherwise not able to stumble up on across all my 4 paid music subscriptions (Apple Music, Spotify, Tidal and Amazon Music). Some that I could not find on these music services, now live on my private Roon server. Mostly ancient multichannel formats, DSD/SACD and vinyl rips. And some precious private live recordings from concerts long gone, as in decades ago.

Tidal is not available in my country.

You could of course use your technical ability to work around that limitation or figure out other ways to pirate the music you like. I just wanted to add another helpful option for self hosters. But thank you for mentioning that Tidal is unavailable in your hitherto unmentioned country, your contribution to this discussion is valuable and appreciated.
