Option/Mod to keep playing Super/Hyper theme during Bosses?

Hi there,

Well, title is pretty much self-explanatory:

Is there an option I have missed, or a mod that stops the boss music from overriding the Super/Hyper music, so that it keeps playing uninterrupted when a boss appears?

I am mainly asking because I occasionally play around with a custom Super/Hyper theme that's a bit longer, and especially cases like Angel Island and Marble Garden where the (mini and normal) bosses make a brief, unbeatable appearance just to play their respective themes are starting to get on my nerves, as those appearances cause the Super/Hyper theme to start over from the beginning.

During the actual battles, it doesn't bother me TOO much, as the battles just last a few seconds and then you power down anyway, but if it also turns off the actual boss tunes while powered up, then that's fine, too.
However, the "boss cameos" are the main culprit that I am after.

Thanks in advance!
