The beginning to the song "Welcome To The Black Parade" that makes every emo lose their shit while crying eyeliner.

Emo: *crying eyeliner*

G-Note 

The G note on a piano is highly important to punk rock/emo rock fans who listened to My Chemical Romance. This note is the opening note to one of MCR's most famous songs, "Welcome To The Black Parade" and while this song is not sad in itself (it's actually very inspiring and upbeat) it saddens the MCRmy/Killjoys because the song was the anthem for that fan base.
If you play it they may cry or get really sad (some over exaggerate and lose their shit so be warned)

Also they will probably mention Geesus/Gerard/Gee at some point.

"Dude, what's wrong?"
"I got g-noted and now I really miss MCR."
"Really, Cas?"
