Quick, have a listen now and see if it makes you feel good!
Scientists at a university in Missouri have identified what they think is the world's happiest song (there's an equation for it apparently).
Queen's 1978 hit 'Don't Stop Me Now' is the one that can bring a smile to anyone's face, apparently.
Neuroscientist Jacob Jolij says that "we generally like songs with a tempo that deviates from the average pop song tempo, that are in a major key, and are a bit more complex than three chord songs, unless the song is a major key".
And 'Don't Stop Me Now' has all those things and more – it's 156 BMP and it's in F Major, which makes it the winner.
Have a listen and release the happy:
