My sister sings 24/7 and it's driving me up the wall

She's a good singer. The only problem is that she literally sings any moment we're home. She also keeps repeating the same line, sings high pitched and loud, etc. Imagine that moment from Ariana grande's song "All im trying to say is that youre my everything babe" and then that build up until and including the whistle note, repeated constantly every day, all day long. It's during calls, while talking, at 1 am, when she's on the toilet (she'll keep it occupied for hours because she's singing). I sometimes can't talk normally with her because she'll randomly start singing again.

I feel bad for feeling this way because she's very talented and the fact that she can sing whistle notes at all is amazing, i might just have misophonia.
