Walking On Air - Kerli

It starts with a deep dark bass, then this sweet voice starts singing these very very dark lyrics:

There's a creepy little house in a creepy little place
Little creepy town in a little creepy world
Little creepy girl with her little creepy face
Saying funny things you have never heard

And then it gets sweet and happy again:

Feel it, breathe it, believe it
And you'll be walking on air
Go try, go fly, so high
And you'll be walking on air

I played this track to death way back when it released in 2018. New artist with this one hit. Never to be heard from again. Ok granted, there's some more music form her, but nothing quite like this. One hit wonder, but what a hit!
