Songwriting money is paid separately from the money your recordings earn, and it goes to whoever wrote the song, not whoever performed it. It arrives through societies, collection agencies and publishers, in several kinds of royalty. If you write, you need to know which ones you’re owed and where to register for them. These guides walk through each kind, the organisations behind them, and the paperwork that settles who owns what share before the song comes out, because sorting it afterwards is slow, awkward and sometimes ends up in court. The earlier you register, the less money you leave sitting uncollected.
