People to me seem to make careers off making noises.
It's not a baaaaaaaad thing, but if you're versatile and want to be considered versatile, then you'll have to learn both. In terms of music. But for pure sound exploration, you don't have to do a damn thing with music.
What you can do, is literally not make any music for like......... six months, and just make some weird noises and stuff. And you'll be pretty good at that point if you attempt to make a weird noise every day. Plus you'll have a decent library to turn to.
Another way is to organize your older sounds into a folder. Go through them, organize it like; subs,bass,leads,pads,melody,sound effect, riser, wubs. Or you can go for a more descriptive approach;atmosphere, chill, RAADD, GNARLY, BANGER, horror, emotional, delayed out, reverbed out. stuff like that.
Analyze your older stuff, because that's in your tool box and is most with in your reach to study.
try to make the sound better with new knowledge or leave it as is.
BTW, song writing is composition. But the song and composition can be what ever you want it to be. you could literally string together fart noises for 4 minutes and call it a song.
