My favourite thing is that they have all sorts of social features so you can really engage with other fans and make lists and explore and do things... but you can also just ignore the hell out of that and buy some music that you like.
IIRC, this is what MySpace was supposed to be in the first place. They made the mistake of leaning into a more general social media audience while Facebook was on the rise, but it seems to me like Bandcamp excels at being what MySpace could have become.
