New analysis from music industry body the BPI shows that last year rock overtook pop for the first time since 2010 in terms of all-important album sales.
Rock - which includes the likes of Mumford And Sons and even Rod Stewart for the analysis - claimed 33.8% of all UK album sales in 2013, up from 31.3% the previous year, while pop accounted for 31%, down from 33.5%.
It comes despite pop taking the top five best-sellers of the year with a trio of Now That's What I Call Music albums and releases by One Direction and Emeli Sande.
But, using figures supplied by the Official Charts Company, the BPI found 40% of the 10,000 biggest albums of the year were rock albums.
Rock landed its biggest share of the album sales market since 2008, when it had 35.7%.
Dance music was the third biggest genre, representing 8.3% of album sales - up 2% in a year thanks to artists such as Daft Punk - and easy listening-style artists, including swing albums from Robbie Williams and Michael Buble were just behind on 8.1%.
It was a different story for singles, where pop remained on top with 36.2% of sales, while rock is at 21.4%.
BPI spokesman Gennaro Castaldo said: "While the appeal of pop remains consistent, the popularity of rock music tends to ebb and flow a little more, reflecting as it does the excitement that can quickly build around new acts as they burst through.
"With Arctic Monkeys now taking on near-iconic status, and the likes of Jake Bugg and Bastille to name a few connecting with a new generation of fans, rock music looks set to enjoy another wonderfully vibrant period."
