Hacking Smash 4 Music hacking?

I saw many videos on Youtube, wherew some guys hacked the music in smash 4. I want to know, how they changed the songs.

They used Cafiine to inject a new .bfstm song (wii u song format). You can read on how to do it here - https://gbatemp.net/threads/the-definitive-guide-to-wii-u-hacking.396828/

Scroll down until you see the Cafiine header.

I have to wait for the actual Kernel Exploit for the latest firmware... sadly I haven´t modded my Wii U before :/
