Bandcamp is good for indie artists and if you want to discover new artists. I’ve found quite a few diamonds in the rough on there. A surprising amount of metal / punk artists sell via Bandcamp if you’re into that.

How is 'just Google it" not a valid option? This is literally how you can find 99% of all problems about the internet especially for finding where to legally buy digital products within the first few websites. You know what is good for business when you’re trying to sell a product? Making sure its one of the first few, if not the first choice the customer gets when looking at the default search engine.

Moving on from that I’m guessing getting in contact with the artist is not an option? Y’know the other 2 points?
