The Queen of Pop keeps piling up No. 1s, Adele puts the 100 in Hot 100 and One Direction continues the tradition of chart-topping boy bands.
'LUVIN' ' AND NOT LEAVIN': As previously reported ,
BOYS CLUB: As Billboard reported Tuesday , One Direction  becomes the first British band to debut an introductory album at No. 1 on the Billboard 200, as "Up All Night" arrives in the penthouse.
(It also makes One Direction the first act with "one" in its name to rank at No. 1 on the tally. In 2001, 112 peaked at No. 2 with the album Part III." Got that?)
The quintet follows in the rock era tradition of boy bands winning the fast-beating hearts of young fans, from the Beatles  and Monkees  in the '60s to the Jackson 5  and Osmonds  in the '70s.
Record labels continued to mine the boy band phenomenon in the '80s, when New Kids on the Block  scored their first Billboard 200 No. 1s, 1989's "Hangin' Tough," which commanded the chart for two weeks. "Step By Step" followed with two frames on top in 1990.
Boyz II Men  reigned for five weeks in 1994 with "II" and for a week in 1997 with "Evolution."
Having formed in the '80s, New Edition  notched its long-awaited first Billboard 200 topper with "Home Again" in 1996 (one week).
Backstreet Boys  sent "Millennium" to No. 1 for 10 weeks in 1999 and follow-up "Black & Blue" spent two weeks at the summit in 2000. Also in 2000, 'N Sync  racked eight frames in charge with "No Strings Attached," while 2001's "Celebrity" led for one frame.
With sales of 12.2 million, "Millennium" is the fourth-best-selling album in the U.S. since the advent of Nielsen SoundScan data in 1991. "Strings" ranks at No. 9 (11.1 million). (And, the Beatles' "1," which contains their Beatlemania/boy band-era Hot 100 No. 1s, places at No. 5 with 12 million).
After a gap in which pop music relied heavily on R&B and rap influences, the Jonas Brothers  brought boy bands back to the Billboard 200 summit in 2008 when "A Little Bit Longer" ruled for two weeks. "Lines, Vines and Trying Times" followed with a week at No. 1 in 2009.
"Boy bands have given us some of the best artists and songs," says CFLZ (Z101) Buffalo, N.Y., music director Corey Mottley. "Justin Timberlake is a great example; I may have hated the members of 'N Sync growing up because they had girls' attention, but secretly I knew all the words to their songs.
"Five years ago, the closest thing we had to boy bands were pop/rock acts," Mottley says, alluding to the pop radio presence of grittier groups like the All-American Rejects and Fall Out Boy before the arrival of such pure-pop acts as One Direction and the Wanted . The latter two groups' "What Makes You Beautiful" and "Glad You Came" rank at Nos. 19 and 3, respectively, on the Hot 100. "Now, we have real boy band material.
"In fact, I would love to see a massive boy band festival with everybody from New Kids on the Block to 'N Sync and Backstreet Boys to boy bands of today," says Mottley.
"Every girl and woman would go crazy. It would be like a passing of the torch."
