Adding new music

So, I've got a .pcm soundtrack that I love (by Zerethn).
I can put the rom in the folder with all the .pcm files & it works great, but is there a simple way to patch this music into the rom with Hyrule Magic?
I can't make much sense of the Music tab...

No, obviously, as PCM is a part of the MSU and MSU is strictly external and needs special emulators or hardware adaptations so it can be loaded. PCMs also take a lot of space. Rom is just 1 or 2, max 4 MB. One PCM can be 20MB. Conker PCM pack is 2GB. "Internal" music for SNES is completely different and it can be done, but we usually all dropped the idea of making new "native" music, since MSU is what prevailed, since it is easier.

I see. Thanks.
