i also love pop punk!!
first off id recommend the band Midtown, especially the album Forget What You Know, and off that album the songs Is It Me? Is It True?, Empty Like The Ocean, Waiting For The News, and Manhattan. The singers other band Cobra Starship is also really good, even though its a whole different vibe.
i also recommend Say Anything, mostly the album ..Is A Real Boy but they have other bangers too like the song In Defense Of The Genre featuring Gerard Way!! off that album id rec Admit It!, Every Man Has A Molly, Belt, Little Girls, and Metal Now. with both of these bands i really think listening to the full albums i mentioned is the best experience, theyre works of art.
then i rec the song Pollyanna by Northstar which is beautiful and so so underrated.
Alkaline Trio is another band i like, though i dont know that many song by them yet. my favorites by them are Radio, She Lied To The FBI, Hell Yes, and Mercy Me.
i hope this helps :) i have been told my music taste sucks, sorry if you hate all of these lol
