Back in 1997 Mmmbop would hit number one in 27 countries for the long haired Hanson brothers. The song has been massively polarising over the years since, appearing both in lists of best and worst pop songs ever. Regardless whether you love it or loathe it there is no denying that this was their first, and last, number one hit. In case you were wondering, apparently an Mmmbop is a unit ot time.
