OK. Here it is. The money stuff...
No yearly registration fees.
99c per track / per store - unlike some services I count iTunes as one store, not all the individual countries as a store.
90% pay thru on all royalties. I'll keep 10% for the work I do on your behalf and so you know that I won't stop trying to sell your music once I've got your rego fees :)
You will also need an ISRC for each song and a bar code for each product you wish to sell online. The first I can do (they're free, you should never pay anyone for them), the second I will soon be able to do, but not yet (they're not free, sadly... check out www.gs1au.org for more info).
Questions or abuse? I'm ready :)
Wanna sign up? I'm waiting :)
