Apples to oranges. Spotify makes money by using your content (as an artist) to sell subscriptions and they kick the artist a $0.003 "commission" on the artists own IP. The wavlake model takes a 10% split which is more akin to what happens with the middlemen in the existing industry taking a cut of profits. Not as egregious as other middlemen though. It all varies but traditionally management will take 15%, distro takes 20%, and the label takes 25% leaving the artist with only 40% before any expenses...
