Um ... Richard, if the US has a compulsory mechanical licence for published works, how is it that I'm dependent on honest folkies to pay me when they record my songs? Because nothing - nothing! - ever reaches me via ASCAP or Harry Fox. And that I know of at least two recordings for which I've never received a cent?   

And on a different tack - to quote again

6. Proprietary Rights in Content on MySpace.com.

This license will terminate at the time you remove such Content from the Services.

Isn't the last sentence significant? So if I remove my content from the services, the license is terminated. Surely?
