Throwaway because I don’t know if they have a Reddit and don’t want to risk it. 

My downstairs neighbor is a DJ or something music related and is frequently playing music very loudly, with bass boosted speakers I might add. Normally, me and my girlfriend really don’t care about the noise. Live and let live, you know. However, recently my work schedule has had me sleeping during the day and working/doing things at night. I went to bed at 11am this morning, and woke up at 1pm to some abnormally loud bass boosted music from my neighbors below. 

I moved to another room in my apartment to try to get away from the noise, but it was seriously loud enough to be heard and felt throughout my whole apartment. Upon realizing this, it seemed like my sleep-deprived state caused some rage to take over and I stomped as hard as I seriously could on our floor. I know this it temper-tantrum behavior, and I normally don’t do that. But I can’t explain what was different this time and caused me to be so angry. Anyways, the stomping was so loud that I’m certain all of the neighbors in our building heard it, and our downstairs neighbors heard it too because they turned the music way down.

Am I the asshole for allowing them to play music normally, not having complained about it in the past until now? I mean, they had no way of knowing I was trying to sleep, and they were playing music mid-afternoon, not at night or anything like that. I feel bad, and want to know if I could be the asshole here or if that behavior was warranted despite having not minded the music in the past.
