is that really the problem here??? i would think spotify uses its market dominance to drive down what they give back to the artists. also, evading tax is not a good idea. it's there for a reason.

Yeah, at least some variations of it are NP-hard. SAT is THE NP-complete problem, but there are some really good SAT solvers around. This basically means: They have a solution that mostly does very well on most instances. But because (probably) P != NP, you will never have a polynomial time algorithm for this.
