When German people go to hell, or skiing, they are forced into little tents, served shitty overpriced beer, and are subject to repeated blows to their ears by a type of parasitic earworm whispered fearfully only in dark circles as "schlagermusik".

Once exposed to it, it eats into their brain and gets behind their eyeballs, forcing them to wear manic grins, and tap tables to the weak, incoherent, barely thought out beats drumming mercilessly into what's left of their soul.

Christian Rock

I'm just going to say Nightcore.

I get that Nightcore has an audience, but what makes it annoying for me is when I am trying to search for an obscure song and think I've found it, only to realize that it's yet another low-effort nightcore remix.

I'm not certain about the most annoying, but this song is pretty bad

A low pitched hum that they don't even notice until they leave and appreciate the silence when they're away from it.

Every Christmas song ever.

Reggaeton

Care to elaborate why?

Just play loud ass black metal. The music doesn't have to be bad, It just needs to scare normies.

Edit: I thought of the most annoying music ever. Crunkcore! Play some Blood on the Dancefloor and people will fuck off to avoid listening to that shit.

There's always the risk that people who visit the house next door are into whatever annoying music you're playing and end up moving there and blasting it for the rest of your life

Baby Shark

I'll raise "Sales Call Abyss", a hold music made for torturing telemarketers if you have access to your work's phone exchange

What's that dolphin-sounding song someone played during sex in that meme? That.

Alternatively, the brown note (assuming it's real).

Or like hardcore noise stuff. Is "Wall of sound" a type of it?

Edit: How could I forget Ram Ranch?

Bagpipes

I mean honestly through a wall the only annoying music is thumpy bass with a big subwoofer. Unless you're playing it suuuuuuper loud.

You need to look up Komar & Melamid. They did market research art, and they commissioned "The Least Favorite Song" after a survey that showed the least favorite features of songs. https://en.wikipedia.org/wiki/The_People%27s_Choice_Music#The_Most_Unwanted_Song

Skrillex

Regeaton and Trap 🤮🤮🤮🤮🤮🤮🤮🤮

Why annoying?

Based on what kind of people they are, you might be able to get away with something else. Maybe play some Christian music if you think they don't want to live next to a god-botherer. If you're bible-belt, put one of those 24 hour Mecca livestreams on loud, and go do your grocery shopping or something.

If you want just plain annoying, you can't go wrong with Justin Bieber or tween pop.

Clown Core is for those with discerning tastes.

*takes extra deep breath

...this is the song that doesn't end / yes it goes on and on my friends / some people started singing it not knowing what it was / and they'll keep on singing it forever just because / this is the song that never ends / yes it goes on and on my friends...

Fuck I hated middle school

If it won't get you in trouble, throw some cheap lawn ornaments up as well. Maybe get creative with loose hubcaps.

It is, and always will be, children's music, like Baby Shark.

Limburg Carnaval music. Hoompapa hoompapa…or Darude - Sandstorm on repeat.

A novelty Christmas song played six months after it spent six plus weeks at number one in the (TOTP) charts. "Aga do" anyone?

[Not sure that any recent charts in this century are worth a damn.]

Can't go wrong with the Goat Simulator soundtrack. https://youtu.be/DHdpuzqD2wg

Joe Pasquale sings it

I'm so sorry.

Modern pop country

Earthbound - Inside Dungeon Man

Love the soundtrack but hate this doozy
