The Knack is Tricky

You'll love this:

1970s one-hit-wonder The Knack had suddenly noticed that Run DMC had sampled their 1979 song "My Sharona" in Run DMC's 1986 hit "It's Tricky." So, even though this was twenty years after that had happened, they decided to sue for copyright infringement.

When companies do this, they call it a "submarine patent" -- when bands do it, should they call it a "submarine royalty"?
