They've taken some flak in the past for their payments to artists and while I'm not following the discussions closely enough to suggest those criticisms are unjustified it does seem that they're not the chief culprit. 30% retained doesn't on the face of it seem unreasonably high, does anyone know how this compares to equivalent services?
Ultimately I don't think disclosure is ever a bad thing and hope maybe this is one more small step advancing the general 'royalty model' conversation.
