The big labels have been greedy money grabbers pretty much since the beginning of recorded music, in the beginning often taking advantage of up-and-coming, young and naive artists by locking them in with long-term, undervalued contracts, not to mention the illegal payola tactics so prominent in the Fifties.I'd rather see these record labels hammered into the ground and artists sign directly with distribution services like Apple Music where the artist receives 70% cut and Apple receives 30%, similar to the App Store. Right now artists make squat from their own music sales and have to do the exhaustive tour circuit to actually make money. At least in most cases.
That original music distribution business model has obviously changed drastically with the advent of downloading and streaming, but the labels' greed doesn't seem to have abated. Eliminating the labels, if that was even possible, and going with your 70-30 artist/distributor split scenario would be a radically positive shift for artists.
Heck, even a 50-50 split would be a monumental improvement for them.
