James Bay's debut album Chaos And The Calm has claimed the biggest artist album release of 2015.
The album has racked up nearly 345,000 combined sales and audio streams since it hit number one on the album chart on its release in March and has spawned two Top 10 singles.
This means that Bay, who won the BRIT Critics Choice Award in February this year, is the fifth best-selling album of the year according to the Official Charts Company, behind four albums released in 2014.
The number one seller was Ed Sheeran's second studio album x, which sold 705,000 copies in 2015 alone and an impressive 2.39 million in total. Sheeran won another accolade earlier this year when one of the album's singles, Thinking Out Loud, became the first song in history to spend a whole year inside the Official Top 40.
As his latest single, Writing's on the Wall, for 007 film Spectre, looks set to make history as the first Bond theme to reach number one, Sam Smith can also celebrate taking second place on the biggest albums of 2015. In The Lonely Hour enjoyed sales of almost 695,000 and spent almost an entire year in the top five, a feat only previously managed by The Beatles.
In third place is Taylor Swift's 1989 and fourth is George Ezra with Wanted On Voyage.
As 2015 enters its final quarter, OMI's Cheerleader is hot on the heels of Mark Ronson and Bruno Mars' floor-filler Uptown Funk in the singles chart.
Uptown Funk spent seven weeks at number one with 1.63 million combined sales and streams this year. After Cheerleader comes Hozier's stirring Take Me To Church with Ellie Goulding's 50 Shades Of Grey soundtrack song Love Me Like You Do in fourth.
Completing the top five single releases of 2015 is See You Again by Wiz Khalifa feat. Charlie Puth, a tribute to Fast & Furious 7 actor Paul Walker who died in a car crash in November 2013.
