The world's first taxi that you pay for by singing is about to launch.
The "singalong shuffle" is an electric car which is powered by sound.
So if you refuse to belt out the tunes, it stops!
The BMW i3 will be unveiled this weekend at the Ruisrock music festival in Finland.
It's part of a promotion by clean energy company, Fortum.
Festival-goers will be able to travel around the grounds in the taxi for free but only if they keep on singing.
And there won't be any fear of forgetting the lyrics and the car stalling - the taxi has a tablet that offers song choices and lyrics.
