"due to the way they calculate their payouts": yes, I'm sure that's the real issue, but the solution isn't a penny per stream. The solution is definitely to redistribute money according to what people listen to, but I doubt the big labels will accept these terms: they are the ones who negotiated, they are the ones stealing from indies.

Best case scenario: indies will get enough pennies so they stop complaining, big labels will continue as today, Spotify will allocate some of its own money to music creation...

and the problem will remain unfixed at the roots.

remember who forced Spotify and others before it, to negotiate a deal at all cost with the Majors or be declared illegal?
