Out of sensitivity to families of the Sandy Hook Elementary shooting victims, the song was pulled from the playlists of many US radio stations, plummeting in the charts.
Ke$ha later took to her Twitter account, where she apologised to those who might be offended by the lyrics of the song and added: "I understand. I had my very own issue with 'Die Young' for this reason. I did NOT want to sing those lyrics and I was FORCED TO."
The claim, which has since been deleted, has now come under further scrutiny thanks to an old interview the singer gave to 95.5 WPLJ.
Ke$ha is featured in the interview - shot in November at the New York radio station - taking full credit for the lyrics in 'Die Young'.
She said: "I definitely make sure that every word rings true to me because I would never want to misrepresent myself to millions of people around the world ... I wrote and wrote and rewrote that song ten times."
