So when I was playing, out of nowhere, the battle music starts playing. I was in my house at Lakeview Manor when it started. I go outside and I fast travel to different places and the music is still playing. I decide to go to the main menu and re-load. It's still playing. I quit the game, shut off the PS4, turn it back on, and load the game again. It's still playing. I disable all the mods that I have. It's still playing. I don't know what else to do and I had to turn the music volume all the way because it was getting so annoying. Has anyone come across this or know how to fix it?

Put on Pantera and pump up the volume!

When this happens to me I open the console and type killallactors. This command kills everything in the immediate vicinity and stops any combat. It always works for me but make a full save before you do this in case it doesn't work in your case.

If it doesn't work you might try waiting for a day, or two days, or even longer. Some enemy might be following you and is having a hard time catching up with you.

You can't open the console in PS4 though right?

Oh, I'm sorry. I missed that. I saw the word "mod" but not "PS4." I'm still stuck in the mindset of mods being PC only. My apologies.

Have you tried travelling to Solsteim or somewhere that forces a change in music? If i remember rightly the music is different in Solsteim so it might work.

I could try that, but I did try getting into a fight with some bandits and while it was in the middle of the battle music track, the music started again when we started fighting. So it was actually playing twice at the same time. So I'm wondering if I try to get other music to play, the same thing will happen.

That sounds like a bug to me, but tbh I don't know how or where to report bugs @ Bethesda. Sad to say.
