UK Singles Chart, 1/17/2009

1. Just Dance - Lady Gaga Featuring Colby O'Donis

After a 3-week stay at the top, last year's X Factor winner, Alexandra Burke, sees her Christmas #1 and best-selling single of the year, "Hallelujah," dethroned by Lady Gaga and Colby O'Donis with the year's first new #1 single "Just Dance." The track is also #1 this week in the US, where it is also the first new #1 hit of the year. Lady Gaga landed at #6 on the BBC Sounds of 2009 poll and is the first artist in the poll's top 10 to have a major hit.

2. Broken Strings - James Morrison Featuring Nelly Furtado

James Morrison and Nelly Furtado take "Broken Strings" to a new peak at #2. The single now far outshines Morrison's previous biggest hit, his first single "You Give Me Something," which peaked at #5. This is Nelly Furtado's first single to peak at #2; the Canadian singer has twice been to #1, with "Maneater" and with Justin Timberlake of Timbaland's "Give It to Me."

6. Issues - The Saturdays

The Saturdays score their third straight top 10 hit with "Issues," further solidifying that they are not just a drop in the bucket but a bona fide new pop act. They are certainly outshining the Sugababes, whose latest single "No Can Do" peaked at #23 last week. While the 'Babes have had singles chart as low as that before, generally they were the fourth singles released from an album; "No Can Do" is only the second single from Catfights and Spotlights.

8. Single Ladies - Beyonce

Beyone scores her 12th top 10 hit with "Single Ladies," which climbs six spots to #8 this week. The singer has back to back singles, as her recent #1 hit, "If I Were a Boy," falls three spots to #7. She's also at #40 with 3-year old single "Listen," which recently hit #8.

10. Let It Rock - Kevin Rudolph (featuring Lil Wayne)

Kevin Rudolph scores a top 10 with his debut single "Let It Rock." The single hit #5 in the US last year.

14. Heartless - Kanye West

"Heartless," Kanye West's second "single" (it doesn't have a physical release scheduled as yet) from 808s and Heartbreak makes a 24-place leap to #14.

16. Kids - MGMT

MGMT's third single "Kids" has been on the chart for 16 weeks now, but it's hotter than ever, rising 21 places this week to #16. I'm not sure what's responsible for the sudden surge in popularity of this single. It is now the group's first top 20 hit, surpassing #22 hit "Electric Feel" as the band's highest-charting single.

29. The Loving Kind - Girls Aloud'

Girls Aloud are up 10 spots to #29 with "The Loving Kind." The single is out in stores tomorrow, and is the biggest competition for Lady Gaga for #1 next week.
