Sounds in game arent mixing well

I have sounds that trigger when close to cars that drive by the player and I also have background music that plays. The car sounds trigger from a collision when the character is near the car. The background music plays from my level blueprint from a play 2d sound node. But for some reason my background sound is constantly interupted and restarts. I do have an overide concurency set and a bypass volume on each sound. So why is my background sound glitching out, is it because of all my sounds in the game. Note there can be multiple cars in the game at once.
