Week of May 1

Two debuts and a new No. 1 frame a week of solid chart moves. Among the week's biggest movers are Bruno Mars' "Talking to the Moon" (17-8) and Roxette's "She's Got Nothing On (But the Radio)" (35-27). The former is not only on Mars' "Doo-Wops & Hooligans" CD but also on the fund-raising collection "Songs for Japan" in an acoustic version. The latter, still not commercially available in the U.S., has made big waves in Europe. Perhaps the same sort of lightning that originally struck Roxette with its worldwide smash "(She's Got) The Look" in 1989 will occur with this comeback hit.

Of the debuts, Adele follows up her former No. 1 hit "Rolling in the Deep," still in the Top 10, with the ballad "Someone Like You." Debuting at No. 39, it's also from the CD "21." Meanwhile, Matthew Morrison of TV's "Glee" joins a long line of actors-turned-singers including John Travolta, David Soul and two artists this year -- Gwyneth Paltrow and Christian Kane -- by debuting at No. 40 with "Still Got Tonight." (Kane, meanwhile, pushes 5-4 in his 20th week on the chart with "Thinking of You.")

And at No. 1, Pink returns with "Perfect." It's her first chart-topper since "Sober" a few years back. Pink becomes the fourth solo female to hit the top in 2011, following Melanie Fiona ("Gone and Never Coming Back"), Adele ("Rolling in the Deep") and the artist she knocked to No. 6 this week, Katy Perry ("Not Like the Movies").
