use File::Find;find sub{/\.mp3$/&&rename$_,substr$_,3},".";

or

use File::Find;find{/\.mp3$/&&rename$_,substr$_,3}".";

if find was declared with proto (&$);

I tried replacing substr$_,3 with s/..-/&&$_, but it modified the first $_ (weird? isn't the comma operator supposed to evalute left, and then right?)

bonus - it passes strict.

Update: Formatting was icky, so I added line breaks.
