I'm not certain of the details, but the copyright rules for music are
different than for other works.  In particular, once you've published
a piece of music, you can't prevent others from performing it -- you
have to license it to all comers for a reasonable fee.  (BMI and ASCAP
handle collecting and distributing the license fees.)  This is unlike
other works, where copyright gives you complete control over who can
and cannot use your work.

Perhaps this is a workable solution to user interface copyrights --
unless you're a diehard Gnuist, the problem with user interface
copyrights is not that they enable the inventor of an interface
feature to make money off it, but rather that they enable him to
prevent others from using the feature at all.  If there were a similar
compulsory licensing feature to interface copyrights, most of their
problems would be solved.
