Rising British pop heartthrob Conor Maynard's debut album "Contrast" (Parlophone/EMI) went straight to the top of the new U.K. chart yesterday (Sunday), while "Heatwave" (One More Tune/Warner Bros./Warner Music) by British rapper Wiley featuring Ms D debuted atop the singles survey.

Maynard achieved his second top five U.K. single of 2012 last week when "Vegas Girl" entered at No. 4. It dipped five places on the new chart, but the 19-year-old from Brighton on the south coast of England made up for it with a bestselling debut for the album. "Contrast" nudged Plan B's "Ill Manors" film soundtrack (679/Atlantic/Warner Music), last week's new entry at No. 1, into runner-up spot.

Emeli Sandé's former No. 1 album "Our Version of Events" (Virgin/EMI) moved up 8-3 as Maroon 5's "Overexposed" (Octone/A&M/Universal) fell a place to No. 4. East London newcomer Delilah, born Paloma Stoecker and a former collaborator of Chase & Status, made a strong solo debut on the album chart with "From The Roots Up" (Atlantic/Warner Music) at No. 5.

Mike Oldfield, who like Sandé received major exposure as part of the performing cast of last week's London 2012 Olympics opening ceremony, opened at No. 6 with Mercury/Universal's new "Two Sides - The Very Best Of" compilation, while his classic "Tubular Bells" re-charted at No. 66. Rap star Rick Ross scored a No. 8 debut with "God Forgives - I Don't" (Def Jam/Universal). "Now! That's What I Call Music 82" (EMI TV/Universal Music TV) started a second week at the compilation chart summit. "Isles of Wonder," Decca/UMC's double CD set of music from the Olympics ceremony, climbed 5-2 on that chart.

"Heatwave" is Wiley's first U.K. No. 1 single, outdoing his previous peak of No. 2 with 2008's "Wearing My Rolex." Before releasing his first solo album in 2004, the grime MC had come to prominence at the forefront of the Roll Deep collective, which also featured Dizzee Rascal.

With 114,000 first-week sales, according to the Official Charts Company, Wiley's new bestseller ended the three-week singles reign of Florence + the Machine's "Spectrum (Say My Name)" (Universal Island), which fell to No. 3. That was also outsold by the new entry at No. 2, "We'll Be Coming Back" (Columbia/Sony Music Entertainment) by Calvin Harris featuring Example.

Returning to the Olympics theme, two tracks climbing strongly after being performed at the London 2012 opening were by "Caliban's Dream" (Locog/UMC) by Underworld, Dame Evelyn Glennie, Only Men Aloud, Evelyn Roberts and Alex Trimble, up 69-12; and the Arctic Monkeys' version of "Come Together" on the same label, up 67-21.
