Подскажите. на каком языке поёт девушка?

Дойч акцент.

Английский.

The kisses of the sun
Were sweet
I didn't blink
I let it in my eyes
Like an exotic dream
The radio playing songs

That I have never heard
I don't know what to say
Oh, not another word

Just la la la la la
It goes around the world
Just la la la la la
It's all around the world
Just la la la la la
And everybody singing
La la la la la And our bells are ringing
La la la la la La la la

Inside an empty room
My inspiration flows
Now wait to hear the tune
Around my head it goes
The magic melody
You want to sing with me
Just la la la la la
The music is the key

And now the night is gone Still it goes on and on
So deep inside of me
I long to set it free
I don't know what to do
Just can't explain to you
I don't know what to say
Oh, not another word

Just la la la la la
It goes around the world
Just la la la la la
It's all around the world
Just la la la la la
And everybody singing
La la la la la And our bells are ringing
La la la la la La la la

The kisses of the sun

Just la la la la la
It goes around the world
Just la la la la la
It's all around the world
Just la la la la la
And everybody singing
La la la la la And our bells are ringing
La la la la la La la la

Around, around, around the world

Может немецкий?))

английский, хотя и с акцентом.

Разумеется, английский. Хотя... почему разумеется? (пожимаю плечами). Просто английский.
