Kanye West's Graduation has pipped 50 Cent's Curtis to the top spot in this week's album chart.
In a top 20 awash with eight new entries, it was the generally less commercially successful West who emerged triumphant in their first week of sales with last week's number one by Hard-Fi falling five places to number six.
Fiddy had previously said he would never make solo records again if Curtis, his third studio album, fails to outsell West.
KT Tunstall's Drastic Fantastic entered the album chart at number three while former Neighbours star Natalie Imbruglia's best of, Glorious, was new at five.
Ultrabeat entered at eight and Kano at 14 while Marc Bolan and T-Rex's best of was new at 15. Italian singer Luciano Pavarotti's The Ultimate Collection was a new entry at 17 following the tenor's death.
In the singles chart, the top four remarkably remained unchanged with Sean Kingston's Beautiful Girls staying at number one for a second week.
Plain White T's came in second with Hey There Delilah while Kanye West's Stronger stayed at number three.
