Week of May 2

Lots of steady chart movement this week, but few big movers (Adam Lambert's "Voodoo" being the exception, up eight to No. 31), so let's concentrate on the debuts.

The week's top debut is a medley of two very popular songs that haven't done as well on my charts as they have elsewhere. Jason Mraz's "I'm Yours" is the longest-running Hot 100 hit in Billboard history (76 weeks), but it never caught on with me, while Israel Kamakawiwo'ole's Hawaiian take on "Somewhere Over the Rainbow" has been a standard in movies and TV shows in the years since the musician's death in 1997. This week, the two songs debut at No. 36 as a medley by the vocal group Straight No Chaser. The 10-man a cappella group originally from Bloomington, Ind., (shout-out to my alma mater, Indiana University!) caught fire the past couple of years on the adult contemporary charts with renditions of Christmas classics. This medley is from their new release "With a Twist."

At No. 37 is a song that also has an IU connection. Alumnus Ryan Murphy created the hit show "Glee," which has spawned more than two dozen Billboard Hot 100 remakes in the past year. The first to chart on my surveys is the all-male remake of "What It Feels Like for a Girl," from last week's all-Madonna episode. The original went to No. 1 in 2000-01. (A medley of two other Madonna hits, "Borderline" and "Open Your Heart" is bubbling under the Top 40 this week.)

The Rolling Stones are back with their first hit in years, "Plundered My Soul," at No. 38. It's a newly unearthed track from the "Exile On Main Street" sessions, with some production updates. Most of the Stones' biggest hits came long before my charts, so their biggest hit here is the ballad "Out of Tears," which hit No. 2 for three weeks in 1994-95.

Christina Aguilera rounds up the debuts with "Not Myself Tonight" at No. 40. We'll see how far this goes; I like the groove a lot but it's a tough song to listen to repeatedly, with a lead-in to the chorus that contains the f-word. (Guess I should see if there's a "clean" version available on iTunes!)

One last note: Keith Urban keeps his unusual chart streak this week with the new No. 1 song, " 'Til Summer Comes Around." What's unusual about it? Every time a song of his has gone to the Top 10, it has gone to No. 1. Otherwise, he misses the Top 10 entirely. This is now his fourth chart-topper, following "Once in a Lifetime," "Stupid Boy" and "Standing Right in Front of You."
