The biggest assumption it made was that people understood the &#x27;sliding pane&#x27; UI as being self evident, and it wasn&#x27;t.<p>Wouldn&#x27;t the only reason there being limited choice be because of the way music deals are structured? I&#x27;m not familiar enough with how those work but having a mismatch of payouts &#x2F; winning labels vs listeners would be a problem.
