On this point, one issue that I think deserves more scrutiny is the centralisation of music playback and archiving. We have increasingly moved away from private possession of the playback medium (both physical storage media and locally-stored files) to streaming from the cloud or downloading from these cloud-based services. The problem I think is with these services, in a position of coercion/power remove these recordings from their services. I think it a real problem for listeners who possess little of the playback media themselves, and not of recordings by the artists in question. It means they are deprived of the ability to choose for themselves. Sure, some might say the free market might adjust for it - but is anyone going to reconfigure their streaming source or move to privately possessing the media for a vanishing minority of recordings? I think not.
