Prior to Bandcamp, the only other times I can recall paying for digital music was for an obscure album on emusic.com, probably around 2007.

The UX of the site and the app are really conducive for discovering new music, and fortunately the audience of BC is such that you wouldn't see a musical equivalent of Pewdiepie or Logan Paul shoehorned into your recommendations. And I especially love that "supporters" (buyers) are the only ones who can post comments on album pages. Keeps spam/trolling/abuse to nearly zero.

Of course, the flip side of that coin is the feeling of doubt around how long a service like this can last without hitmakers that bring in larger audiences and revenues.
