Billboard Hot 100, February 20, 2010

The effects of last week's post Grammy Award sales continue to be felt on the Hot 100, perhaps moreso, since last week there was only Sunday night and Monday to factor in.

1. Tik Tok - Ke$ha

Ke$ha's "Tik Tok" spends an 8th week at #1. That's the longest a single from a solo female artist has been at #1 since Beyonce spent 10 weeks at #1 with "Irreplaceable" 3 years ago.

2. Imma Be - Black Eyed Peas

"Imma Be" is up two notches to #2. The song's fast rise is quite impressive, considering this is the album's fourth single, and has been available digitally for many months now.

3. Need You Now - Lady Antebellum

The country threesome rises 5 spots to #3, finally besting the single's first peak when it charted as a country hit in November. "Need You Now" is this week's digital gainer.

7. Hey, Soul Sister - Train

Train climbs two spots to #7, matching the peak they achieved 3 weeks ago. I'm still a little amazed to see this in the top 10, which I believe is mostly a sales-based phenomenon at this point. Why the sudden interest in Train? They haven't had a major hit since 2001 when "Drops of Jupiter" hit #5.

9. I Gotta Feeling - Black Eyed Peas

You know you have a massive, massive hit on your hands when it can manage to appear in the top 10 almost 8 months after its first appearance there ("I Gotta Feeling" debuted at #2 in late June 2009). It's been on the chart now for 35 weeks, and it's never appeared outside the top 20.

11. In My Head - Jason DeRulo

Jason DeRulo is on the brink of scoring his second top 10 hit, as "In My Head" rises 3 spots this week.

16. Telephone - Lady GaGa feat. Beyonce

New high-water mark for "Telephone," up 3 this week. It's one of three Lady GaGa singles in the top 40 this week, with "Bad Romance" still in the top 10 and "Paparazzi" holding on at #33.

18. Glitter in the Air - Pink

Her Grammy performance may have been the oddest of the night, but that didn't stop fans from gobbling up "Glitter in the Air," the song Pink performed in a next-to-nothing outfit while hanging from a spinning ribbon secured to the ceiling. The track debuts at #18 this week, one notch below the #17 peak of her last top 40 hit, "Please Don't Leave Me." This is the fourth top 40 hit from Pink's fifth album, Funhouse. Only her second album, Missundaztood, produced as many top 40 hits. "Funhouse," another Funhouse single, peaked outside the top 40 at #44.

20. According to You - Orianthi

Australian singer Orianthi rises a notch to #20, scoring her first top 20 hit. I'm sure this will be top 10 soon.

28. Use Somebody - Kings of Leon

At 54 weeks, "Use Somebody" is the oldest single in the top 40. It's up 3 this week, surely still benefiting from last week's Grammy Award for Record of the Year.

30. Haven't Met You Yet - Michael Buble

Did you see Michael Buble on SNL 2 weeks ago? He was great, and the appearance helped "Haven't Met You Yet," which climbs 6 spots to #30.

36. Say Something - Timbaland feat. Drake

Timbaland and Drake climb 10 spots to enter the top 40 at #36, becoming Timbaland's fifth top 40 hit (as a performer) and Drake's 8th.

37. Naturally - Selena Gomez and The Scene

Disney's latest star scores her first top 40 hit. Selena Gomez stars on the Disney Channel's Wizards of Waverly Place. Along with her band, The Scene, she climbs 18 spots back into the top 40 this week (the single initially peaked at #29 three weeks ago). It's a frothy pop song with a touch of dance and rock (think Miley Cyrus's "See You Again").

40. Breakeven - The Script

In 2008, Irish pop/rock band The Script had a fairly impressive European launch. Their biggest hit, "The Man Who Can't Be Moved," hit #2 in Ireland and the UK. Now the group finally scores their first US top 40 with "Breakeven," which was their third single, peaking at #10 in Ireland and #21 in Britain.
