There are now several ways to go over holding 4 songs in your head. Currently a non-AT can get up to 5, an AT can go all the way to 7.
If it is considered a bug: the boolean_modifier("additional song") returns true when you have the AT passive skill Mariachi Memory, but was originally designed to denote you had a La Hebilla del Cinturón de Lopez equipped.
So there is no apparent way to tell if you have a La Hebilla stacking bonus currently, other than have_equipped(), and likewise with the zombie accordion stacking bonus.
The passive skill Mariachi Memory also raises some questions about the "Four Songs" modifier. With it you can hold four songs by default but the boolean_modifier("Four Songs") returns false. It only returns true when you equip one of the "four instead of three" pieces of equipment. However if you have Mariachi Memory and equip a "four instead of three" you can actually hold "five instead of four" songs.
I'm not sure what the best course of action is but the current setup doesn't seem ideal anymore

Revision: 8190
Added "Additional Song" boolean modifier, currently only provided by the AT
epic accessory. I'm assuming that any future sources of this enchantment
won't stack.
