Had enough of noisy neighbours took it into my own hands

So i moved into my block of flats about 3 months ago. Theres a group of young adults that are constantly sitting on the stairwell behind my bedroom smoking, laughing loudly, running about. One of them lives above me and plays loud music that they rap along to past hours CONSTANTLY. Ive tried reasoning and explaining i have a 2 year old and i am disabled, we deserve peace to no avail. ive called noise patrol who they have just argued with and continued once they have left. Well tonight I had enough, tonight im home alone with my two year old and ive spoken to them once already. So I chose welcome to the jungle by guns n roses, the most rock song i could think of, one that my son is familliar with. Then I turned my tv up to 100, which ive never done before, its pretty loud on 20 and has good bass for a lower end model samsung. I have misophonia but I was so angry it didnt affect me. Then just to add insult to injury I started screaming the lyrics, i cant sing for love nor money. Once the song ended. I turned my tv off. One guy said "wtf?" And they turned their music off and have been silent since. I said to my husband if this continues i will turn my sound system on and play baby shark on a loop. Im not playing games anymore. Best part is, the two year old is still fast asleep.

Tldr: you wanna torture me with your gangster rap, im gonna torture you with middle age white guy music.
