I'm surprised this still hasn't been implemented, given there must be some industry pressure to do so. Under Android, all(?) the various consumer wireless audio implementations (Sonos, AirPlay, etc.) require users to either use a vendor-provided music app (which vendors don't want to deal with maintaining, nor do users want to be forced to use), or one of the few music apps that implement their standard. It's a frustrating mess, all the more frustrating given that the limitation seems to exist only to prevent ripping of copyrighted audio, regardless of how beneficial the legitimate uses are.
