I love the music in this game as much as anyone else, but I play Sea of Thieves every day and sometimes I want to listen to something else while I play...but I still want to know when I get a kill or of one of my teammates got it instead.
Simple suggestion, just move the kill sound from the music sound group to the SFX sound group. I can't remember if the cannon hit sound is also in the music group, but it should also be in the SFX group if it is not. Basically, the music slider should only control the background music, not any sound cues triggered by player action.
