This was part of new guidelines introduced on April 1, 2002, which also included a label that featured "Edited Version Also Available" next to the Parental Advisory seal.[20] Sometimes, an artist will deliberately change the title or artwork of an edited version as to reflect the censorship. For example, as well as removing the marijuana leaf, the cover of the edited version of Dr Dre's 1999 album 2001 has a big box reading "CENSORED VERSION" while the edited version of 2 Live Crew's 1989 album As Nasty As They Wanna Be not only changed the title to As Clean As They Wanna Be, but also censors part of the cover photograph with a blue bar that has a disclaimer that reads "THIS ALBUM DOES NOT CONTAIN EXPLICIT LYRICS".
