Thrills, Kills and Sunday Pills is the fourth studio album by Australianrock band, Grinspoon. It was released on 20 September 2004. The album represents a dramatic change in style towards a more mainstream, teen orientated image. "Hard Act to Follow" and "Hold on Me", were minor hits for the band, and represent a more easy listening rock style for the band. "Better Off Alone", a ballad rock song, was also a minor hit. There is a lack of any songs in their older metal style.
As of 2008, the album has gained mostly positive reviews due to it containing the pop of New Detention while placing themselves in a more teen-oriented direction. However, there have been complaints by fans explaining that Grinspoon were "selling out".
