Yeah, I was that loud neighbor for years (reformed now in my old age).
In college, I lived on the top floor of an apt bldg and had a music studio set up in my bedroom, like a giant 10 foot x 4 foot wooden cube I constructed from scratch to record my rap music. It had the egg shells all over the walls, but it was by no means soundproof. So I would be recording these hardcore raps at all hours of the day and night. Just the filthiest lyrics. And I didn't always get a verse right on a first take so I had to re-record a lot of verses until I got them perfect.
I had music to make, baby, this is a college town, Idgaf. I got a show to do. Over the course of two years, I recorded an EP and a full album. And, you know what? I don't regret it at all, would definitely sacrifice everyone else's peace to finish my music projects again (I still bang them shits like once a month).
It got to the point where I had to totally ignore the vibes I was getting from the neighbors and their subtle hints that my music was too loud, like they wouldn't come right out and say it so I would just remain willfully ignorant and just continue business as usual. There was a couple below me who would be fighting all the time with each other, like screaming at each other (one time the cops came and took the dude away) so Idk what came first, my music or their fighting, but I justified it like, "If they're gonna fight, I'm gonna make my music." One time I crossed paths with the guy in the hallway -- he was kind of muscular, looked a little bit like Henry Rollins but with longer, greasy-looking hair. Anyways, I tried being really nice and the vibes I got back from him were just the worst. But that guy beat his gf up probably (I mean, the cops took him away), so that guy can go to hell.
That couple moved out finally as I was finishing my last few tracks on my full-length (I still needed to find my single). Then some single mom moved in downstairs with a baby. She didn't put up with it so much. She would bang on her ceiling (my floor) with a broom because I was evidently waking up the baby with my raps.
Then she came upstairs and confronted me, standing there in my doorway, going on and on about something like I don't pay enough attn to the needs of the other tenants in the bldg or some shit (Idk, I wasn't really listening to her). Anyways, I apologized and took a break for a cpl days before I got back to it (the broomstick banging from below resumed). Me finishing the album coincided with graduating college, so I vacated the apt shortly thereafter and moved back to my hometown.
I don't record music at my current apt but I definitely used to blast it. Then I learned my lesson when one pretty passive guy with whom I shared a wall moved out (quite certain due to me playing music) and got replaced by a total nutjob.
This new guy was a coke head and would confront me point blank about my music, like wait outside my apt for me to come home and block my path up to my apt to force me to deal with him. Tensions escalated (I remember him banging pots and pans against the wall one day) and we would have these music wars where I would play my music then he would play really loud music on the other side of the same wall, then I would turn my music up and he would turn his up and so on and what have you.
But he was the kind of guy who was like "No Snitching" so I knew it would take a lot for him to complain to the landlord. He was also not very bright about being tactical. So one night, during the height of one of these "music wars", I turned my stereo of and just recorded him playing his music at level 10 with my phone. I got like two minutes of footage of him just blasting ICP (he was a juggalo).
So, when he did ultimately go to the landlord complaining about how loud my music is and she came to talk to me about it, I played her the video of "Magnets, How Do They Work?" shaking the picture frames on my wall for two straight minutes and he ended up getting thrown out the apartment (lol).
I still live at the same apartment but I did learn a valuable lesson and got wireless headphones after that guy. Now I'm the quietest neighbor of all time. I had a good run for years and got out the loud neighbor game before the loud neighbor game got me.
The last neighbor, however, got addicted to meth and is currently incarcerated.
