Pretty partial to Japanese pop myself. I'm learning Japanese partially so i can understand the songs. Yoasobi's songs are a good general recommendation, I would recommend Yoru ni Kakeru, Gunjou, and Seventeen.

French?

• Florina - Va Va Vis
• The Longest Johns - Santiano (only partly in french, but damn bro)
• Cedric Watson - La Vieille Chanson De Mardi Gras

Poi E - Patea Māori Club

some of the ones that spontaneously come to my mind are:
- https://www.youtube.com/watch?v=Fpu5a0Bl8eY
- Ievan polkka
- https://www.youtube.com/watch?v=r0Mo4QSedFo
- Naruto's second opening

Tanz mit Mir by Faun

Cocteau Twins. I'm pretty sure she just gave up using actual words entirely at some point.

Rammstein - Du Hast

Anything from Ningen Isu.

Ningen Isu - Heartless Scat

Jane Air, Junk

Rammstein, Moskau

Afterhours, Vedova Bianca (There's an English version that was used in Mr. Robot)

Rammstein - all songs 🙂

The entirety of NieR and NieR Automata's vocal tracks. Most of them are actually just gibberish.

La Vie en Rose - Eddie Piaf

Ievan Polka

Du Hast - Rammstein

I think that's a pretty good spread

Asilos Magdalena by Mars Volta

I like all their stuff, but that’s the only one I can think of that is completely in Spanish

Too much kpop and jpop to list, but Kent (swedish) has a lot of good songs: Stanna Hos Mig, 400 Slag

Great thread - I'll throw in a few although I'm late to the party.

Gaspar Nali - Abale Ndikuwuzeni

Anything from the Afro-Cuban All Stars or Buena Vista Social Club albums

Orchestra Baobab - Sey

Mory Kante - Yeke Yeke (Hardfloor mix)

Lexicon Avenue - Here I Am (Rutabaga mix)

Leva's polka

I'm partial to Klingon Opera.

du

Nanook - Ingerlaliinnaleqaagut

Taikatalvi by Nightwish

Mostly songs from C. Tangana , especially the songs from his "concert" on TinyDesk.

Jonas Dichoso - Empilight

https://music.youtube.com/watch?v=kENZU2VKrf4&si=9B86AAEYqA6ZO9Vl

Jamal Kudu

Most things by Snow Tha Product - start with 'Butter' or 'No Cap In My Captions'.

Ichiko Aoba - Windswept Adan. The whole album is magical.

A lot of j-pop

Anything by kælan mikla out of Iceland is good. Definitely Draumaudis/dream dance

Aural Vampire from Japan is a lot of fun too. Hard to pick just one. But kerguelen vortex is a good starting point.

Ruina Imperii by Sabaton

Rammstein, most of what eluveitie makes and inabakumori makes...

There's a bunch of hardbass I like that's usually in Russian or some other slavic language Mostly listen to Uamee
