bcond_with and bcond_without are pretty easy to use and works well, I
(personally) don't understand why we have another variants. 
But they have one little trick: : "never use without_foo, _with_foo nor
_without_foo, only with_foo." . Also reading /usr/lib/rpm/macros, at
line 111, we got all examples that we may need. 

we don't have "without" operator only "with" so at least 
%if %{without mp3} ,  should be: %if ! %{with mp3} ... 

Cheers,
