Now that 2015 is way behind us, it’s time to review the year’s biggest music hits.

And the winner is Adele, whose newly released “25” was the best-selling album. The British singer sold more than 3 million copies in the first week of its release, setting a record.

Adele has not made her third album available on streaming platforms such as Apple Music, Deezer and Spotify — following in the footsteps of Taylor Swift.

The song you couldn’t escape

“Uptown Funk” by Mark Ronson and Bruno Mars was the year’s biggest single. It was also the most played video clip, with more than 1.1 billion viewings.

Coldplay to play at Superbowl halftime show

‘Adventure of a Lifetime’ is the first single from Coldplay’s seventh album “A Head Full of Dreams”.

Still, it’s selling like hotcakes and Coldplay will perform at the Super Bowl halftime show next February.

Love me like you do

Another bestseller was Ellie Goulding’s “Delirium,” the British pop singer’s third studio album. Her single “Love me like you do” was recorded for the soundtrack to the film “Fifty Shades of Grey”. It topped the UK charts for four weeks and peaked at number three in the US.

It has also just been nominated for a Golden Globe for best original song.

PSY is back and going viral again

Of course, how could we avoid PSY? The South Korean singer who brought us Gangnam Style is on track for another hit with his latest single “Daddy”. The clip, with its own crazy dance steps, has been viewed more than 40 million times since it was uploaded on YouTube at the end of November.

Bieber beats the Beatles

Justin Bieber has been topping the charts with a string of smashing hits and has even beaten the Beatles with 17 songs in the US Hot 100 in a single week.
