C'mon by Panic! At The Disco featuring Fun. 

I swear, Brendon is trying to murder that piano

"try not to mistake what you have with what you hate" that is some amazingly deep stuff right there

I love how Brendon gets so into the song and the music...he's so passionate and it makes me cry

Literally Dallon just in background like “hello darkness my old friend” 😂
