As previously reported, Lady Gaga becomes the first artist in the 17-year history of Billboard's Pop Songs chart to notch four No. 1s from a debut album, as "Paparazzi" rises 3-1.

The singer - recently honored as Billboard's Rising Star - previously led Pop Songs with "Just Dance," "Poker Face" and "LoveGame" from her debut release, "The Fame." The set has sold 1.56 million copies in the U.S. to date, according to Nielsen SoundScan. The album will be re-released in expanded form as "The Fame Monster" Nov. 23, and its newest single, "Bad Romance," this week bounds 38-25 on Pop Songs.

Four days after the album's re-release, Lady Gaga will kick off her 38-date Monster Ball tour in Montreal. The North American leg of the tour runs through Jan. 13 in Detroit. The tour will continue Feb. 18 through March 8 in Europe with shows in cities including London, Belfast and Dublin.

Since the Pop Songs chart debuted in October 1992, two artists prior to Lady Gaga had plated three No. 1s from their first albums: Ace of Base and Avril Lavigne (pictured, left). (Alanis Morissette also enjoyed a trio of leaders from her first U.S. album, "Jagged Little Pill").

Interscope president/promotion Brenda Romano and senior vice president/promotion Chris Lopes told Billboard.com, "we're overjoyed about Gaga's unprecedented achievement. It's phenomenal, but not surprising. Gaga's an awesome talent, with boundless creativity and an uncanny ability to make her visions come to life.

"She's a great person, and we couldn't be happier for her. Our staff deserves praise for its hard work and dedication, and radio deserves thanks and appreciation for all its support.

"We can't wait to see LG at the Monster Ball. It's going to be a phenomenal tour!"

Pop radio programmers are equally impressed with Lady Gaga's unrivaled start at the format.

KMVQ (Movin' 99.7)/San Francisco played "Paparazzi" the most times - 131 - of all Pop Songs reporters in the current chart's tracking week (Oct. 26-Nov. 1), according to Nielsen BDS.

"Lady Gaga has come on to our station like a tornado," says Movin' program director Michael Martin. "When you make hit records, the audience responds, and we would be foolish not to give them what they want."

KAMP (97.1 Amp Radio)/Los Angeles has spun "Paparazzi" the most times to date - 880 - of any chart reporter through Nov. 1. John Michael, the station's assistant program director, says that Lady Gaga is "definitely one of our most identifiable artists."

"What makes her different from every other artist is that she, quite frankly, sounds different than every other artist. In a world driven by people who tend to gravitate towards what is proven and comfortable, Lady Gaga has released a record full of hits that doesn't sound like anything else out there right now.

"So, even at single number four, there's still a freshness to her music. I'm sure there are musicians in a studio somewhere biting her style even as we speak. The Lady Gaga wannabes are coming!

"That will put the ball back in Gaga's court and force her to re-invent herself. The good news is that she seems to be completely up for the challenge."

Of all the stations currently on the Pop Songs reporter panel, KHTT (K-HITS)/Tulsa was the first to play "Just Dance" (April 3, 2008).

"From the first listen, I knew that 'Just Dance' was a K-HITS record," says KHTT operations manager Tod Tucker. "Even though no one, including myself, had heard of Lady Gaga, I put it on the air, and the phones started blowing up.

"Tulsa can't get enough of Lady Gaga, and I'm proud to say we took the lead in playing the biggest female pop artist of the 21st century!"
