Ke$ha's new single "Die Young" has been pulled from radio stations in North America after last week's school massacre in Connecticut.
Ke$ha claims she never wanted to sing the song because of its title, but was forced to. That message has since been deleted.
TMZ was first to spot the dip in airplay for the song. It started off at number 3 on the radio playlist chart last Friday with 167 million listeners before the shooting. By Saturday it dropped by 3 million, and by monday dropped by another 19 million.
One expert said a drop of this magnitude is "extremely rare," and hasn't been seen since the Dixie Chicks were dropped from country radio after insulting President Bush.
Ke$ha responded to the radio blockade on twitter:
Billboard caught a screenshot of the message before it was quickly deleted.
It was replaced with a more diplomatic tweet: "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."
