I don't really care if this is a fairly generic question, I'm still curious.
For me it's quite a bit of early to mid 00s rock music, particularly alternative rock, pop-punk, and emo. A lot of it has to do with this being music I feel really shaped me in some fashion, helping me to just really feel emotions I have a hard time expressing myself (well more so I have difficulty expressing them IRL). Play me stuff like Remedy by Cold , Diary of Jane by Breaking Benjamin , or I'm Not Okay by My Chemical Romance and fuck dude, I'm back to being a Hot Topic teen again.
