Well they definitely distribute and market... and the creator would be the artist (most of the time). So you’re just talking about producers / labels I guess? Definitely not what I would assume when you say industry...
That is the music industry. The rights holders and creators (IP owners). The distro channels are part of it, but wouldn't necessarily change (you want to distribute everywhere you can). If google bought all the music IP in the world, the distro channels are unchanged (unless Google decided to limit distribution!).
