The english language literally steals words from other languages and adopts them.

I can keep going but I think you get the point. Some english songs do throw in other languages at times too.

Many Asian songs, especially Japanese and Korean will often include english because they are all taught english in school and english is used in the business world. When visiting Korea and Japan, in major cities, a large amount of signage will include english to aid tourists.

Umm.. don’t plenty of English language songs do this too?

You know how many French words/phrases I hear in English songs? Coup de x, raison d'être, déjà vu, etc

It's not unheard of there to be English language tracks that drop in random French, Italian or Spanish words and phrases

It's just regular cultural exposure to other languages ultimately. No rule says you need to stick to one language in a song, so some musicians throw in some stuff from other languages they've heard, because why not

Not just songs, but all the other languages showing up in English comes up conversationally too! When you did something wrong, there's the "mea culpa". Or in the courts, there are tons of Latin phrases like "nolo contendre". I've had "perritos calientes" (hot dogs, literally hot puppies) in Spain, but never have I had a "giant cheese" (quesadilla) or "little donkey" (burrito) in the states. And we just borrow other phrases as-is like "Je ne sais quoi" and schadenfreude.

As if US music isn't full of random Spanish words

Oh well, que sera sera.....

This is more of a question than a thought, but apparently the English language borrows from lots of Latin-ish and other alphabetic languages of centuries past.

Yes English is awkward. I didn't write the rules or definitions either. 🤷

English contains a veritable shitload of loanwords as well.

But you're not wrong when you think they're trying to be cool. You'll hear this most often in hiphop, which started in English and not every language lends itself to rap. So they throw in an f-bomb here or there. Imitation is the highest form of flattery type stuff.

Also, English is the most commonly learned foreign language on this planet. A lot of contemporary music genres came out of North America. I would say internet culture is most pervasive in English as well. A lot of tech jargon becomes English loanwords in other languages. There are reasons beyond wanting to sound cool as well.

♫ Voulez-Vous Coucher Avec Moi Ce Soir ♫

Yes, I can imagine. It's done literally all the time, in every genre.

Styx would like a word.

you know the saying that english is five languages in a trenchcoat that drags other languages into alleyways to ruffle through their pockets for loose nouns?

english is basically the european pidgin language.

Maybe English speaking people with tattoos of Chinese letters is the equivalent?

That strongly depends on culture. In poland this doesn't happen at all. On the other side, in Japanese works I've seen not only English words included, but completely fake languages (Nier Automata Ost) or pseudo languages faking Latin or English (Madoka Ost, Hellsing TV intro)

Domo arigato, Mr. Roboto.....
Michelle, ma belle, Sont des mots qui vont très bien ensemble....
Psycho Killer, Qu'est-ce que c'est?....
Voulez-vous coucher avec moi, ce soir?....
Jeux sans frontières, Hans plays with Lotte, Lotte plays with Jane...
Eyes without a face, Les yeux sans visage....
This indecision's buggin' me (esta indecisión me molesta)...
Ooh, appelle-moi, mon chéri, appelle-moi, Anytime, anyplace, anywhere, any way....
and many more.

In Dutch we have a term called "borrowed words", those are words we stole from a different language.

For example "Portefeuille" is a Dutch word, but it originate from the French. Another example is "computer", we do not have/use a Dutch variant.

Using these words in a song will sound like your described. But it's actually still Dutch

I don't have to because there are? Does no one recall those guts who were Kung Fu fighting? The rumor is that those cats were fast as lightning.

Not just songs. F***ing english "sprinkles" are everywhere and it's annoying beyond words. "Myllärin by Helsingin mylly". 11 cases out of 10 it sounds imbecile, not cool.

Multilanguage songs are the best thing. It's part of artistic expression, and a reminder to ourselves that at some point, all humans came from a different place.

It's almost always bigger languages.

Karel nese asi čaj by Jiří Korn and Vilém Čok

This Czechoslovak song is mostly in Czech but also features number sequences from (in order of appearance): German, French, Italian, English, Czech. (The younger singer, Vilém Čok, was not explicitly anti-Communist but the censor ruined his career anyway because this song was "too weird", and it didn't recover except for the 1-minute intros to Ducktales and Chip'n'Dale he sang in 1990. That was recently ruled illegal even by 80s standards but the censor got a slap on the wrist. Čok was audibly laughing at the verdict because there was little else he could do.)

Another non-English ones that come to mind are 1980s parodies of the countless Italian hits from back then (Sarà perché ti amo, Made in Italy, Ti amo, L'italiano etc.) by Jaroslav Uhlíř and Karel Šíp with some self-referential humor. I think that's why my aunt, a language teacher, learned Italian first and only got good at English after failing to find a job in the 00s.

But otherwise, the foreign-language content people mostly consume is English, and the songs reflect that. (Even imported words − do you think „fajn“ (pronounced fine) as seen in „One, two, three, všechno, co je fajn, se smí“ (a line from the aforementioned song) is from German fein meaning “delicate”?)

Same reason some English songs have random words in other languages I guess.

Yes, but english has like 30% or original germanic roots and rest is a mix of french, latin, spanish, greek and you name it. I would hazard a guess that english is one of the most loanloaded languages in the world.

I was in Germany once many years ago, and was riding the train with a bunch of college kids. They only swore in English, everything else was German.

Spanish phrases or even entire Spanish verses aren't unheard of in English-language music

I don't have to imagine it.

I listen to Mars Volta. They like to use random, non-English words a lot. But they usually use them correctly in the English sentence if you look up what the word is, which is not at all like most Japanese music I've heard injecting English into the Japanese. Most of the time, the Japanese music I listen to is being really nonsensical and seems to just throw the english in because it sounds cool, not because it fits any meaning.
