NEW YORK (Billboard) - A week after Lady Gaga set a milestone on Billboard's Pop Songs radio airplay chart, Ke$ha has rewritten the record.
Last week, Lady Gaga's "Bad Romance" made chart history for logging the most weekly plays in the 17-year archives of the tally, registering 10,859 plays in the tracking week of January 11-17, according to Nielsen BDS.
This week, Ke$ha's debut RCA Music Group hit "TiK ToK" claims both the summit from "Bad Romance" -- the tracks swap places at Nos. 1 and 2 -- and establishes a new weekly play record of 11,224 in the week January 18-24.
"TiK ToK" has spent the past five weeks at No. 1 on the Billboard Hot 100.
Two weeks ago, Ke$ha became just the 12th woman to send her debut single and album to No. 1 on the Hot 100 and Billboard 200 respectively, when her introductory set "Animal" arrived atop the latter list.
