I sympathise with the artists who are losing out on money, OTOH would 55 million people have BOUGHT 'Ooh baby I love your way'?
What can be done, though? Short of a technological apocalypse I can't see people - especially those who have grown up with streaming - being happy about returning to the old model of 15 quid for an album.
Same thing is going to happen with movies/TV soon, if it hasn't already.
But yeah, not an ideal state of affairs for musicians/artists - and perhaps not even for listeners/viewers.
