Muse and Olly Murs have nine Number 1 albums between them, but which act will add to their impressive tally on the Official Chart?
Rock gods Muse have five records to their name, with their last five studio albums all reaching the top spot. Their eighth studio collection Simulation Theory is one of this week's big releases, and is available in a range of collectable limited edition formats.
With four consecutive chart topping albums to his name, can Olly Murs extend his own streak at Muse's expense? Olly's sixth studio set titled You Know I Know also comes with a second disc of his greatest hits, and features the single Moves ft. Snoop Dogg.
Muse and Olly face competition from The Beatles' whose classic self-titled album (also known as The White Album) gets a 50th anniversary reissue. The golden anniversary repressing of Sgt. Pepper's reached Number 1 last May.
The likes of Jonas Blue, Jeff Goldblum, Imagine Dragons, Train and Architects also have new albums out, while 2018 Number 1s from Rod Stewart and Jess Glynne are rolled out on vinyl.
On the singles front, Cheryl puts out Love Made Me Do It, her first single in four years. There are also new tracks from Little Mix, Jennifer Lopez ft. Bad Bunny, Fickle Friends, CNCO x Meghan Trainor x Sean Paul, and Kelly Clarkson shares her take on Never Enough from the upcoming The Greatest Showman - Reimagined album.
