Premise: Aha Shake Heartbreak is the sophomore studio album by American rock band Kings of Leon. It was released in November 2004, in the UK and February 2005, in the United States. It is the only album by Kings of Leon to have a Parental Advisory label because of the strong language in "Taper Jean Girl", "Rememo", "Soft", and "Four Kicks". The cover is reminiscent of Queen's "A Night at the Opera".
Hypothesis: Since then Kings of Leon have released 2 more albums with  Parental Advisory label
