The song scientifically made to make your baby happy

It's the first song scientifically composed with babies' happiness in mind.
'The Happy Song' is billed as the first ever scientifically tested track to rid your little ones of their tears and sadness - and turn them into giggling bouncing babies.
Singer Imogen Heap, working with UK brand Cow & Gate, created the two-and-a-half minutes long jingle, made up of a "bouncy" major key melody, and lyrics talking about the sky, the sea, fun animals, and vehicle noises.
The brand also asked 1,000 parents to name noises that made their babies happy, and the results showed that sneezing (51%), animal sounds (23%), and laughter (28%) were most popular.
