Okay, Peter...we know you’re still alive, and you don’t like Rush. Now back to obscurity.
He’s about as famous as a rock musician in his 50s can be. He may be able to prevent the US of his music in the manner Rush used it because he could argue it is synchronization to another performance (Rush’s voice-over) rather than a standalone performance. Synchronization, most common for the use of songs in ads or movie soundtracks, requires a specific license which the holder of copyright in the recording can grant or withhold as he or she sees fit. Standalone performance on an over-the-air radio station require no licenses — the holder of the copyright in the composition (songwriter or his or her assignee or successor) gets an automatic formula-based royalty, the holder of the copyright in the particular recording gets nothing.
