Peter Frampton: 55 million streams and I got paid $1700
The Offspring sold rights to their songs for $35 million a while back.
Clearly music IP is still worth something.
Also, as a counterpoint, I wonder what number you would arrive at if you totalled all the recordings sold multiplied by the average purchase price, and divided by the average number of times the purchaser listened to the song. So maybe the good ole' days weren't much better.
And what about radio?
