Before He Cheats but the mashup version with Warriors.

From the few artists I know in this thread and any self-descriptive titles, this is going to be rather out there but…

Breaking Benjamin and Three Days Grace are what a friend and I agreed is the perfect breakup music. I think it came up because it made me feel better during a breakup but I didn’t want to continue listening to it to avoid getting sick of it and it losing the effect next time. Or something, idk I was a teenager :p

BB: I will not bow • Crawl • Blow me away
3DG: Break • Scared • Riot

Didn’t know them at the time but Amity Affliction probably fits here as well. Soak me in bleach or Pittsburgh, for example

Unbreak my heart - Toni braxton

Its not right but its okay – Whitney Houston

Before he cheats - Carrie Underwood

Baby Bitch by Ween

If you’re the one who wanted to break up: Want You Gone. The song Glados sings from Portal 2.

If not: 50 Ways to Say Goodbye by Train

You Outta Know by Alanis Morissette

Ok just thought of another one that will be good if you like country that is pretty twisted.

Weird Al - One More Minute

Dry your eyes - The Streets

You Oughta Know if you’re mad about it

Don’t Speak if you’re sad about it

Can’t beat I Will Survive by Gloria Gaynor.

it’s literally called the Break Up Song :)

Go Your Own Way - Fleetwood Mac

Unhinged: You Oughta Know by Alanis Mortisette. Listen closely to the lyrics for way too much information.

Hinged: Hard to Say I’m Sorry by Chicago. Such a sweet melody that I’ve heard it playing on weddings, of all places…

Somebody That I Used to Know came out during my only breakup and it was everywhere, so I feel biased toward it.

However, I’m a huge They Might Be Giants fan and they have some good ones:

They’ll Need A Crane, Lucky Ball & Chain, and Let Me Tell You About My Operation stand out, but there are plenty of others.
