Week of Feb. 7

Judging from this week's top two debuts and biggest mover, you could easily surmise I was one of the roughly 26 million people who watched the Grammy Awards this past Sunday. That's actually not the case: I've fallen out of the Grammy-watching habit the past several years. But I did hear good things from Facebook friends about the Lady GaGa/Elton John and Pink performances. So when iTunes made the GaGa/Elton duet available, I listened to enough to realize I'd like it, and then after hearing the audio version, I knew I'd have to download the video, too. That duet, more than anything else, has persuaded me to give GaGa more credit than I have been. I've thought of her as more of a Katy Perry combination of modest talent and a flair for hype and flash. It could be that Madonna is more of a model for GaGa. We'll see in the years to come.

Meantime, this week the medley of "Poker Face/Speechless/Your Song," coming in at No. 20, is the highest debut since December 2006 when "Dear Mr. President," by Pink featuring the Indigo Girls, entered at that spot. Of course, at that time, the chart was a Top 30 rather than Top 40 so GaGa/Elton's achievement is even more significant comparatively.

Speaking of Pink, she enters at No. 25 with "Glitter in the Air." That's still good for a third-place tie for highest debut in the past two years; only the GaGa/Elton duet and Susan Boyle's No. 23 debut for "I Dreamed a Dream" performed better. With its No. 25 debut, Pink's song ties "4 Minutes" by Madonna, Justin Timberlake and Timbaland. "Glitter in the Air" is the fourth song from Pink's latest CD to make my charts, following "So What," "Sober" and "Please Don't Leave Me."

Finally, Grammy performing artists Lady Antebellum take their crossover hit "Need You Now" from its debut last week at No. 36 to No. 23 this week. With that kind of momentum, they could well be joining country crossovers from Reba McEntire and Tim McGraw in the Top 10 in the next few weeks.
