Katy Perry's "Teenage Dream" becomes just the third album in the 18-year history of Billboard's Pop Songs chart to yield a quartet of No. 1s, as "E.T.," featuring Kanye West, ascends 2-1.

The song follows "California Gurls," featuring Snoop Dogg, the title cut and "Firework" to the top of the Nielsen BDS-based mainstream top 40 radio airplay ranking.

The only prior albums to generate four Pop Songs No. 1s apiece were Justin Timberlake's "FutureSex/LoveSounds" (2006-07), with "SexyBack," "My Love," featuring T.I., "What Goes Around...Comes Around" and "Summer Love," and Lady Gaga's "The Fame" (2009), courtesy of "Just Dance," featuring Colby O'Donis, "Poker Face," "LoveGame" and "Paparazzi."

(When "E.T." ascended to the top of the Billboard Hot 100, where it has reigned the past three weeks, "Teenage Dream" similarly became only the ninth album to produce four No. 1s in the chart's 52-year archives).

"E.T." marks Perry's sixth Pop Songs No. 1 overall. She posted two toppers from her prior effort, "One of the Boys" (2008-09): "Hot N Cold" and "Waking Up in Vegas." With six chart champs each, Perry, Beyonce and Mariah Carey trail only Rihanna, the leader with eight No. 1s - and whose "S&M" dips to No. 2 after a week at the apex - and Lady Gaga and P!nk, each with seven.

Lady Gaga's "Judas" concurrently debuts at No. 30 on Pop Songs after just three days of airplay. The song tallied 1,405 detections on 118 of the Pop Songs panel's 132 reporting stations (translating to an opening audience of 13.6 million) after it was serviced to radio and released to iTunes Friday (April 15).

While notable, the arrival of "Judas" can't match the frenzy of the record reception given to prior single "Born This Way," the lead cut and title track from Lady Gaga's third studio album, due May 23. Likewise after only three days of airplay, "Born" stormed Pop Songs at No. 14 with 4,602 plays (39.3 million audience impressions), the highest detections total by a debuting title in the chart's history.

"Born" descends 4-7 on Pop Songs this week. The song topped the tally for one frame three weeks ago. (It led the Hot 100 for six weeks).
