Change music in maps made by OTHER people

[Jace-Inumara]

So I am in this one group with their own map and music. HOWEVER, I wish to NOT have the music they have. However, I did the thing where you replace the other file for the specific group with a new one but...
I want to add more that one to a map when they only had one assigned to each...

Is there a way to add more to the soundtrack or am I stuck with one song for each map because that's how they did it?

p.s.

I went into the music.cfg file and tried adding music THAT way too (nada)
Placed files in both music AND sounds after doing above (nada)

note: The replace worked, but I want more than one song ;n; so keep that in mind.

It depends on how many songs they have within their map. If there is only one song, then it wouldn't be possible to have multiple songs; pretty self-explanatory.

Yes, you would need to have permission to the map yourself to add songs.

Here is a video done by Red, it's useful and tells you have to add music to costum maps. But, obviously, you should ask the owner of the maps first if you can change the music.
