@SrRochardBunson In our own experience we don't enjoy the time sink, clunk and difficulty using it when submissions are offered via it. It does not help enforce good meta or attribution data as well.
It is not comfortably usable, extendable, efficient, well federated, or easily discoverable front-end for artists and labels.
Smashing donation links into it or trying to integrate a shop into the experience might not be on balance healthy
Very much an online personal jukebox at the core.
