Kaisers Orchestra - Bak et hallelujah

Everything by Wardruna. Gregorian chant and medieval music, particularly by Hildegard von Bingen. Music by Enya in Gaelic.

That's a solid "The entire Caramba" album.

You might've heard (of) Habba Habba Zoot Zoot; well, they made an entire album of "plausible sounding" songs in German, Japanese, Finish, American, Russian, etc. It's really quite hilarious.

Oye Como Va - Santana

I know enough Spanish to understand the lyrics now, but loved that song before I knew what it was saying.

I don't speak Spanish, but when I heard Colores by Ska-P ("Por la libertad es fundamental la diversidad") I was instantly in love. The music is great and the lyrics seemed straight up fire.

Then I translated their songs and now they are my second favourite band, after RATM.

A Chitón - On repression and censorship in the name of security

El Vals del Obrero - The Workers Waltz, on unity of the working class

Songs from Negura Bunget, First Fragment, and newer stuff from Vildhjarta

Yeah!
I've had "V blbym veku" from Xindl X in a playlist for 10 years.
I don't understand a single work, but it just speaks to me for some weird reason.

The artist Lescop is great. I know some french but not enough to really 100% follow the lyrics

Bad Apple!! by Alstroemeria Records featuring nomico

Lots of Polish music:

Sexy Doll by Republika
Mówię Ci, że by Tilt
Fajki i Alkohol by Andy
Zima by Natalia Szroeder
Gdzie jest biały węgorz ? by Cypis

I gave up trying to learn Polish because of its immense difficulty. I only speak English fluently but I've taken up an interest in Esperanto.

Always liked the melody to this 王七七Wang QiQi song:

Any song that's on my playlist and not german or english ;)

Though specifically Akatsuki Records (JP), CrazyBeats (JP), several Vocaloid produces I can't remember.

J'en parlerai au diable • Johnny Hallyday

A lot of classical music

This is a significant fraction of my music collection.

Pretty much the whole soundtrack to Clair Obscur: Expedition 33. It's all done up in French and I only know bonjor, baguette, and fromage. But it just sounds right for the mood of the game :o

Ay Que Doler by Los Chunguitos. Such a banger and I always sing along but no idea what they're saying

Baba Yetu, the Swahili opening to the game Civilization 4. Wikipedia says it's the first song made for a video game to win a Grammy.

Does this count?

All of Francoise Hardy's album Soleil. Absolutely lovely singing voice.

I always thought Regin Smidur by Týr captured exactly the kind of vibes I'd expect from Viking metal. But I've never known what the lyrics are about, and probably don't want to.

A lot of songs come to mind, actually.

But if I had to pick just one, it would be MC Solaar's Carpe Diem.

My French is shaky at best, so back when I stumbled upon MC Solaar (maybe it was via Bearshare), I could barely understand the gist of what was said - and even with a much better understanding, many of the "retro" references in this song specifically would have made no sense to me.

But it evoked a weird sense of nostalgia in me - a longing for a time/things, that I had no connection to (so I shouldn't even feel any nostalgia):

PS: If I had to pick something more popular, it would be Plastic Love by Mariya Takeuchi (got recommended by YouTube back when it made its first comeback wave in 2011, I think).

A bop is a bop

MONO NO AWARE - かむかもしかもにどもかも！

No clue on the lyrics but the melody along with the lyrics are excellent

Blueprint Supreme

SKAI ISYOURGOD & AR LIU Fuyang

I have no idea what they're saying, but I know it slaps.

Brutal 6 - Todo en mis Manos.

Olivia Lufkin - Stars Shining Out.

Anna Tsuchya - Kuroi Namida

I'm surprised that people can answer with only one or a few songs. I don't "discriminate" music by language at all, I listen to a ton of music from all over the world in more languages than I can say. One very good place to find good international music is the YouTube channel My Analog Journal: https://youtube.com/@myanalogjournal

Locutorio - Sara Socas (España)

I caught some Icelandic rap the other night on that global radio website and now I need to find it. I caught some Algerian rap - rap again, even though it's usually not my thing - a few months back, too, and it was awesome.
