Ed Sheeran was the most-played artist of 2021 in the UK, and also claimed the year's most played single with Bad Habits.
It is the second time he has claimed both accolades, previously achieving the double in 2017 with the release of his album Divide and hit single Shape Of You.
Adele is the only other artist to have topped both charts in the same year, with Rolling In The Deep and the popularity of her album 21 in 2011.
It is the fourth time in five years that the 31-year-old pop superstar has been the UK's most-played artist, having been temporarily dethroned in 2020 by Dua Lipa.
The annual charts are compiled by music licensing company Phonographic Performance Limited (PPL) from music usage and airplay data from radio stations and television channels as well as public performance locations.
