My 3 roommates are 14 14 16 years old. We are males(if this matter) (I am 18).

They listen music, often very loudly. I will graduate in this year, and I am very tired thanks to the cutted weekends. 

Three weeks ago while I am sleeping, they came in with their rap music and spoke loudly. I woke up and told them that I am annoyed by their habits of listening music.
Usually I tell them that I am annoyed by their music, and they tell me that they all 3 like this music and I should f*ck off.

Today I came back from shower, one of them came back too and opened the window. I told him to close it till I dry myself properly and he told me that its my annoying smell of cigarettes (recently picked up cigarettes)

Am I the asshole for not caring their discomfort?
