Ke$ha says she understands that her hit song "Die Young" "is now inappropriate" following the shootings last week in Newtown, Conn.
The singer said in a Twitter post Tuesday night that she's "so so so sorry" for anyone affected by the tragedy.
I'm so so so sorry for anyone who has been effected by this tragedy.and I understand why my song is now inappropriate. words cannot express.-- ke$ha(@keshasuxx) December 19, 2012
Earlier Tuesday, Ke$ha tweeted that she had her own issues with "Die Young" due to the lyrics, but that she was "FORCED TO" sing them. That tweet was deleted a short time later.
Ke$ha's spokesman said the 25-year-old had no comment Wednesday morning.
"Die Young" is intended as a party anthem and is No. 3 on this week's Billboard Hot 100 chart. But radio stations began to pull it and other songs with potentially upsetting lyrics after 20 children and six adults were killed Friday at Sandy Hook Elementary School.
Rich Minor, the program director and morning host at WDAQ radio in Danbury, Conn., told Billboard the song was no longer in the station's rotation.
"We've been playing it before Friday but not since and I think we're now done with it," he said. "Even though it's a fun pop/dance record about seizing the moment, all people are going to hear right now is those two words in the title."
Another song that has lost airplay is Foster the People's "Pumped Up Kicks." According to TMZ, the track -- which includes the lyrics, "All the other kids with the pumped up kicks / You better run, better run, faster than my bullet" -- has been pulled from Los Angeles station KISS-FM's rotation in the wake of the Connecticut shooting.
