If you have led Zeppelin, Rolling stones etc. On your streaming service you don’t expect to have less streams for rock or metal but I don’t think a lot of modern metal and rock bands don’t have that many streams amd besides that the bands that are popular and have a lot of streams are already ok your somewhere else or not touring at all when this festival happens. O would refuse to play a 50th anniversary of a legendary festival aswell because you know before it even started that it probably won’t be As great. the original festival was a complete mess and free because they did not sell enough tickets (Jimi Hendrix played at 9 am in the morning on Monday even though he was scheduled to play Sunday evening)
