There is nothing to get away with. Hosting small/shitty bands is not a money making proposition for Spotify. Most bands will never make money on Spotify, in spite of Spotify enabling them to do so. They just suck. And I think it is so cool that anyone can suck and still have their music be ubiquitously accessible on the premiere music platform, without real hurdles and at no cost, in (roughly) the same way that any big artist can.
