of course a direct purchase from bandcamp, either an album or a shirt/merchandise is the best. avoid amazon at all costs. purchasing from itunes is decent. if you want to stream, pay for an account on tidal, it’s the one that pays best of all the streaming services. the very worst is spotify and right under spotify youtube/youtube music. it’s better if you just grab the album from piratebay at that point, since youtube is the only one making money.
