NO. 1 . . . EVERYWHERE: Gotye's smash "Somebody That I Used to Know" adds another chart-topping feat under its belt, as it rises to No. 1 on Adult Contemporary. In May, it became the first song to hit No. 1 on Alternative Songs, Dance Club/Play Songs and the Billboard Hot 100. Thus, "Somebody" is now the only tune to have topped all four of the above-mentioned tallies. It's one of the most crossed-over hits in Billboard history, having also climbed to No. 1 on Triple A, Rock Songs, Mainstream Top 40, Adult Top 40 and Dance/Mix Show Airplay.

So, what airplay charts has "Somebody That I Used to Know" NOT been No. 1? Among our other lists, the tune went as high as No. 10 on Rhythmic Songs, and No. 36 on Latin Songs. (Seeing English-language hits on the Latin Songs chart is fairly common, though they often don't reach the top 10.)

BLINDED BY THE 'LIGHTS': The blindingly successful "Lights" by Ellie Goulding continues to barrel up the chart track, motoring 5-2. Meanwhile, on the Adult Top 40 chart, the song makes the longest climb into the top 10 by a woman in a single chart run as it motors 11-8 in its 28th week. (Sarah McLachlan's "I Will Remember You [Live]" took 29 weeks, but in two separate chart runs.)

Among all acts, "Lights'" rise is the slowest to the region since OneRepublic's "All the Right Moves" also took 28 frames on April 24, 2010. The all-time most-leisurely route to the top 10 is owned by Augustana's "Boston," which waited 32 weeks (Jan. 27, 2007).

'GOIN' ON AT NO. 1: Just two weeks after Katy Perry set the mark for the most No. 1s in a row on Dance Club/Play Songs (with 10), Jennifer Lopez ties that feat with her latest leader, "Goin' In." Lopez's current No. 1 streak began in 2007 with "Que Hiciste."

She followed it up later that year with "Hold It, Don't Drop It," "Do It Well" and returned in 2010 with "Fresh Out the Oven" (under the pseudonym Lola, featuring Pitbull) and "Louboutins." In 2011 she topped the list with "On the Floor" (featuring Pitbull), "I'm Into You" (featuring Lil Wayne)" and "Papi." Earlier this year she hit No. 1 again with Pitbull, this time with "Dance Again."

Before her streak started, she claimed three more No. 1s: "Waiting for Tonight" (1999), "Feelin' So Good" (2000; featuring Big Pun & Fat Joe) and "Get Right" (2005).
