When Bloomberg reported that Spotify would be upping the cost of its premium subscription from $9.99 to $10.99, and including 15 hours of audiobooks per month in the U.S., the change sounded like a win for songwriters and publishers. Higher subscription prices typically equate to a bump in U.S. mechanical royalties — but not this time.
By adding audiobooks into Spotify’s premium tier, the streaming service now claims it qualifies to pay a discounted “bundle” rate to songwriters for premium streams, given Spotify now has to pay licensing for both books and music from the same price tag — which will only be a dollar higher than when music was the only premium offering. Additionally, Spotify will reclassify its duo and family subscription plans as bundles as well.
Although it's far from the best, Deezer has a much fairer royalties compensation method, which is more closely based on a per-user basis, rather than total amount of minutes listened (that Spotify currently employs).
This isn't super related to OPs post but I thought it might be worth mentioning aswell.
I've been using Deezer for a while now. Not only is the streaming quality (FLAC) much better but also the artist compensation much fairer. Plus, they at least act as if they actually cared for the customer...
