The copyright situation with music is kinda broken, different parts of the performance get quite different priority when it comes to copyright (many core elements of a performance get basically no protection, whereas the threshold for what counds as a protectable melody is absurdly low). Especially this means its less than worthless for some genres/traditions: for jazz and blues, especially, a huge part of the genre and culture is adapting and playing with a shared language of common riffs.
