aside from bandcamp (which I love, but a lot of artists aren't on there), other places I've found where I can actually purchase and download music:
- Qobuz has a lot of artists from larger record labels who aren't on bandcamp, they're always the second place I look when I'm trying to find an album
- Ototoy has a lot of Japanese artists, some of their stuff is region-restricted and not available for purchase in the US but I've been able to get some good music there
