In my design class one of my classmates plays the animal crossing theme on loop everyday. I've expressed to her several times that it really grates on my nerves and makes it hard to work. I've never pushed the issue too hard, just put in headphones when I could. 
I've told her about my sensory issues (especially auditory ones). I've really tried to let her know that I can't handle listening to it all class everyday. 
Today was an awful day for me, sensory wise. When I walked into class she wasn't playing it but she started playing it not long after I got set up. I groaned loudly and was just gonna put on my headphones but she said "Don't groan about it, it's cute." I blew up telling her that I literally hated the tune, and that I wished she wouldn't play it. Another student scolded me but I feel justified. I know shouting wasn't the best solution but I've been trying to get her to stop playing the song since first semester.
