9: Hanson – Mmmbop
Hanson had a large number of singles and albums charting fairly highly since they debuted in 1992. Starting out as three teenagers with Justin Bieber-eque voices, they successfully managed to make the transition to three grown men with much manlier voices. Mmmbop was their first hit way back in 1996 and once you realise that the singing blonde is one of the brothers and not their distant cousin Alice, you can truly get into this bebop re-invention.
