The boy bands - some of whom, admittedly, are now a long in the tooth for that epithet and all of whom appeared in the same episode of The X Factor results show 15 days ago - are Take That, JLS and Westlife.
Take That's Progress opened at number one last week with a century high first-week sale of 518,601, and remains at the summit with second week sales of 208,219. It advances 9-4 on the year-to-date chart and is a shoe-in to move to the top of the list in the next fortnight.
After consecutive number ones with first two singles, The Club Is Alive and Love You More, JLS' second album Outta This World debuts at number two on sales of 152,473 copies. That's well below the 239,643 copies their introductory, self-titled 2009 album sold on its debut week. The latter album falls 38-48 but with sales increasing for the seventh week in a row. Its career sakes of 1,241,701 include 8,608 in the latest frame.
With first single Safe sliding 10-21 (18,090 sales), confirming its status at the lowest charting single to date by Westlife, the Irish band's new album Gravity debuts at number three.
Their 11th straight top three album since their self-titled 1999 debut, it sold 94,894 copies last week. Their last album, Where We Are, opened at number two a year ago next week, on sales of 135,511, and has sold 491,779 copies to date, making the smallest contribution of any album to their career sales tally, which stood at 11,522,797 before Gravity's release. Westlife's best first week came in 2000 when Coast To Coast sold 234,767, and its worst came in 1999, when Westlife sold 83,032 copies.
Knocked out of the medal positions by the boy bands, Susan Boyle's The Gift dips 3-4 with sales up slightly (69,453), while Rihanna's Loud fades 2-5 (68,069 sales).
Four years after The Black Parade provided them with their first Top 10 album, My Chemical Romance fall short with follow-up Danger Days: The True Lives Of The Fabulous Killjoys, Debuting at number 14 (32,766 sales), it can't match the initial thrust of its predecessor, which debuted at number two on sales of 85,805 copies, and has thus far sold 603,808 copies, making it the band's biggest seller.
Russell Watson's album career sales topped the 3m mark on Wednesday (24th) - the same day he turned 44. He racks up the 11th Top 20 album of his career - and his second in a week - as La Voce, his introductory Epic album, debuts at number 13 (37,524 sales). It overshadows The Platinum Collection - which debuted last week at number 14, and now slips to number 17 (23,187 sales).
Irish country/MOR crooner Daniel O'Donnell is the most prolific chart maker of the 21st century, chalking up 12 Top 20 albums since 2000. Even more impressively, the 48-year-old from Donegal has charted an album on the Top 75 every single year since his 1988 chart debut - that's 23 years in a row, and something no other act can match. His latest release O Holy Night: The Christmas Album hasn't increased that tally of Top 20 albums yet - it debuts this week at number 21 (20,677 Sales). It is, however, his 26th Top 40 album, and his 30th Top 75 entry. That's the most for an Irish act, putting him ahead of Foster & Allen, who drew level last week, when Magic Moments became their 29th chart entry. Both acts started out on Ritz, reached a wider audience through TV advertised albums on Telstar and currently record for the DMG TV label.
Kanye West's third album, Graduation, debuted at number one on sales of 84,611, in 2007, but follow-up 808s & Heartbreak arrived at number 11 (44,720 sales) in 2008. Critically acclaimed for its quality and diversity, and on schedule to debut at number one in America on sales of more than 5000,000, his fifth album, My Beautiful Dark Twisted Fantasy can't arrest his UK slide, debuting here at number 16 (24,236 sales).
Also new to the Top 40 on a busy week: Josh Groban's Illuminations (number 30, 15,769 sales) and Pink Friday by Nicki Minaj (number 34, 13,304 sales).
Housing more number ones - 12 - among its 44 tracks than any previous volume, Now That's What I Call Music! 77 gets off to a suitably brisk start, debuting atop the compilation chart on first-week sales of 333,772. That's 15.40% up on 2009 equivalent Now! 74's first week sales of 289,231, and 33.94% above immediate predecessor Now! 76's opening volley of 249,195. The last Now! album to open with a higher sale was Now! 70, which sold 383,002 copies to debut at number one in August 2008.
Overall album sales increase for the sixth week in a row, climbing 17.05% week-on-week to 3,736,406. That's their best level thus far this year but 12.90% below same week 2009 sales of 4,289,991.
There's a charity handover at the top of the singles chart, with JLS' Children In Need single Love You More slipping 1-3 (60,592 sales) to be replaced by The X Factor Finalists 2010's recording of Heroes to benefit the Help For Heroes charity.
Originally a 1977 number 24 hit for David Bowie - who wrote the song with Brian Eno - Heroes sold 144,014 copies last week, recording the third highest weekly sale of any single in 2010. It is the 20th number one spawned by The X Factor, of which JLS have contributed most (four), while Leona Lewis and Alexandra Burke have had three apiece. Olly Murs has had one, but his second single, Thinking Of Me is unlikely to add to that total, as it debuts at number four (59,657 sales) following his performance of it on The X Factor results show eight days ago.
While Heroes is number one, another 1970s song - Elton John's Your Song - climbs 3-2 for Ellie Goulding on sales of 72,292 copies. After a fortnight at number two, Take That's The Flood surrenders, falling to number six (47,041 sales).
Further down the Top 40, there are debuts for Do It Like A Dude, the debut single from Jessie J (number 25, 13,123 sales), Brett Domino's tongue-in-cheek tribute to I'm A Celebrity drama queen Gillian McKeith (number 29, 11,361 sales) and Doncamatic by Gorillaz feat. Daley (number 37, 7,262 sales).
The number of Beatles songs in the Top 200 slides from 32 to 12, with Let It Be (up 46-38, 7,186 sales) taking over as the top title from Hey Jude (40-47, 6,216 sales). Meanwhile, the band's 1967-1970 and 1962-1966 albums rise 33-28 and 32-29, with sales up 86.8% and 82.6% respectively, at 17,374 and 17,011. They are joined in the chart by the 1962-1966/1967-1970 box set, which debuts at number 59 (6,182 sales).
Singles sales fall 1.88% week-on-week to 3,025,758 - 11.73% above same week 2009 sales of 2,708,023
