How to not have music drown out my voice.

As the title says. My personal preference is to have music playing while I talk and I've messed with it before posting until I thought it was fine, but then I go back to watch a video after uploading and the music is almost completely drowning out my voice.

I said screw it and didn't do any music in a video but honestly I just don't like it.

Any advice?

And yes my lighting and audio is pretty bad in most of my videos, I've figured it out a bit better since then... I'm just looking for advice on background music.
