There were three other Top 10 entrants. US singer-songwriter Jason Derulo came in at No. 4 with "It Girl" while singer-guitarist James Morrison was at No. 5 with "I Won't Let You Go."

Irish singer-songwriter Damien Rice was up from No. 39 to No. 9 with "Cannonball," originally released in 2002, after the song was covered by 23-year-old Welsh maths teacher John Adams on "X-Factor" last week. Kasabian are back at the top of the album chart with their newly released "Velociraptor." The Leicestershire band scored a No. 1 one with "West Ryder Pauper Lunatic Asylum" in 2009.
