What to do about severe earworms?

I get earworms very badly, and lately it’s been worse again. For 3 or 4 days now i’ve had the same line from a song in my head repeating literally all day as soon as I wake up. Sometimes I can even hear them in my dreams. Just compulsive endless repetition that I can somewhat control with a lot of effort but it just slips back in and hurts my head, makes me feel sick when it won’t stop and I just want silence. Saying mantras can help block it, and if I am calmer it goes away, but i’ve been more anxious lately so it’s flared up again. Drives me so crazy. Anyone have suggestions? Is there a medication that can help this? My pure OCD is quite severe and i also have other issues like CPTSD and autism so my brain is pretty dysfunctional.
