For discovery, check out https://rateyourmusic.com/! You can rate music and then use automated suggestions, or better yet, go on albums you like and check out profiles of people that made reviews that resonate with you for other stuff they like. It’s old-school, based on humans! You can look into charts by genres as well.
Instead of collecting a physical music library, you can consider DRM-free digital as well. You can buy albums in such formats at Bandcamp, Qobuz, 7digital. Of course you can sail the high seas as well once in a while. Personally I’m proud to support artists, but I have much less scruples concerning copyright over music made by musicians that have passed away.
Break it, confirm it’s broken, fix it back. Makes me feel better every time.
