I did. Yet none of them were to my satisfaction, which is why they haven't gained the noteriety they could have.
It's easy to do though, here's what you'd have to have the Addon perform:
o Add a SwitchFix watch (check Visor).
o When Switch happens, have SwitchFix toggle the music/sound off, then on.
What'll happen is that whenever the sound is turned off and on, it actually fixes the music issues. It'll disable any looping music until the next time it loops but this is actually a good thing because you won't get deafened by the megaphonerific volumes that might slip through in the half a second before they're corrected.
I'm not up to making this, not really. If anyone else wants to do it though, I'd be happy to help them.
I have to be honest with you, I don't like the way Mozz's works. It basically sets console values, over and over, on every frame redraw. It's quite the resource drain from what I saw. It'd probably be good though if he rewrote it to only fire when it needs to fire. As it stands though, it reminds me of my old SiMiHiOi, which I abandoned for the same reason.
