The UX challenged has been solved, though; there are multiple well known websites selling music and which allow you to bundle all songs in a single order. You just can't force the artist to use them.
Yes and no - streaming and iTunes are pretty good for most things "mainstream" music. Soundcloud though: there's no excuse for them at least not to _try_. Just like for her, ads and passive aggressive song selection are killing the experience.
Then for content at large, there's pretty much everything to do. Not surprised if Stripe and ApplePay, both focused on this micro-amount market, take it all.
