Los Angeles-based quartet Far*East Movement is set to move to the top spot of the Billboard Hot 100 with its debut single "Like a G6" (2-1) when the chart is released tomorrow (Oct. 21). The act knocks out fellow newbie Bruno Mars, who falls to No. 2 after four weeks at No. 1 with his premiere single as a lead act, "Just the Way You Are." 

Among multi-member acts, Far*East Movement is the first to take its initial chart appearance to No. 1 on the Hot 100 since D4L hit the top with "Laffy Taffy" in January 2006. Though "G6" is pushed down to No. 2 on Digital Songs by Taylor Swift's new arrival "Back to December," it shifts 223,000 (up 1%), according to Nielsen SoundScan, for its best single-week sum to date.

Cali's Far East Movement Rockets Up Hot 100

A week after opening at No. 2 on Digital Songs and No. 8 on the Hot 100 with "Speak Now," Swift claims her third chart-topper on the former list- all occurring this year- as "Back to December" debuts with 242,000 downloads. "December" starts as the Hot Shot Debut at No. 6 on the Hot 100, extending Swift's record for most top 10 debuts in the history of the chart to seven. 

Her latest track is the third pre-release single from "Speak Now," which drops on Monday, Oct. 25. One more title, "Mean," was issued on Oct. 19, so expect another high Swift debut next week. Swift had previously topped Digital Songs with "Today Was a Fairytale" in February and "Mine" in August. She has yet to top the Hot 100, however, having peaked at No. 2 with "You Belong with Me" and "Today Was a Fairytale."
