Billboard Hot 100, April 16, 2011

1. E.T. - Katy Perry feat. Kanye West

Katy Perry spends a second week at #1 with "E.T." Last week, I skipped a Hot 100 recap and instead wrote about her pretty amazing feat of having four #1 hits from one album, making Teenage Dream only the ninth album to ever do that. This week, it joins an even more exclusive club within that set, becoming one of just four albums with four #1 hits that all spent more than 1 week at #1, a feat she shares with George Michael's Faith, Mariah Carey and Usher's Confessions. As for Perry's guest star, Kanye West, this is his fourth #1 hit and his second as a guest performer after his first, "Slow Jamz" with Twista and Jamie Foxx. The track is this week's Airplay Gainer, and it's currently the fastest growing track at top 40, where it's gaining 2002 spins at present according to Mediabase. Surely it will also soon become her sixth #1 hit at top 40.

2. S&M - Rihanna
3. Just Can't Get Enough - Black Eyed Peas

Two singles are teed up to try to unseat Perry at #1. It will be a tough sell for either to accomplish this next week though. Perry is #1 at sales, #6 and airplay and the greatest gainer on both of those component charts. "S&M" is #1 at radio, but lagging behind the other two in sales. "Just Can't Get Enough" is second place at sales but not yet top 10 at radio. I think this all adds up to a third week at #1 for "E.T." next week.

6. Look at Me Now - Chris Brown feat. Lily Wayne & Busta Rhymes

"Look at Me Now" climbs a notch to #6. It's Chris Brown's 10th top 10 hit and his first since "Forever" hit #2 late in 2008. His last album, Graffiti, failed to chart any top 10 hits.

10. Rolling in the Deep - Adele

Adele scores her first US top 10 hit as "Rolling in the Deep" climbs 7 notches to #10. The single peaked at #2 in Britain, playing second-fiddle to her bigger #1 hit, "Someone Like You." Globally, "Rolling in the Deep" is the bigger single, having hit #1 in Belgium, Germany, Italy, The Netherlands and Switzerland.
