In what is traditionally a high-volume download week thanks to shiny new MP3 players under the tree and download cards stuffed in stockings, a digital sales mark has fallen by the wayside.

Rookie pop singer Ke$ha's TiK ToK shifted 610,000 digital tracks for the week ending December 27, according to Nielsen SoundScan. That's the highest weekly sum by a female artist since tracking began in 2003, and the second-best overall after Flo Rida's Right Round sold 636,000 this past February. Coincidentally, Ke$ha was an uncredited singer on the track.

TiK ToK eclipsed the female mark set by Lady Gaga with Just Dance exactly a year ago.

Ke$ha's hefty download sum will ensure TiK ToK's place atop the Billboard Hot 100 singles chart for a second week when that chart is released Thursday. The song previews her debut album Animal, which is set to hit stores on January 5.
