Spotify covers are already sent to BS5, BV11, V1 - should be no problem, regarding copyright, with Beo6...or do I miss something?
Not knowing anything about the actual problems or agreements... BV11 and V1 are the Spotify players, they are not transmitting anything anywhere when they show the artwork. Similarly with BS5 which cannot be used alone, you can consider it just a wired display for the actual player (because that's what it is) and not much different from the display screen of a desktop computer running a Spotify application.
