Apple is offering indies a firm, non-negotiable royalty rate of $0.0013 per stream on iTunes Radio, according to contract details confirmed by Digital Music News early this morning. That corroborates information disclosed by a separate source earlier this month (and published by Digital Music News); though the latest information now comes in writing, on an actual contract.
Apple is also offering shares of advertising revenue and an increase after the initial year. Here’s the more detailed breakdown of the rates that Apple is offering.
Keep in mind, this is just the (non-negotiable) form contract being sent to indies (and non-major artists). Major labels have been granted entirely different terms, based on earlier negotiations.
