more likely to listen to it because there is an increased attractiveness to the music. There are many adolescents that follow the "forbidden fruit" theory as a way to either lash out at their parents or to make themselves feel more mature than they are. They may use explicit music as a way to be rebellious and to appear cooler to their friends, even if they are much too young to be exposed to that kind of music. The "tainted fruit" theory states that the child will see the label and immediately know to avoid this kind of content because it is inappropriate for their age. These children are the ones who see the label and do not even acknowledge this album or these songs because they know that it is not made for them. The Recording Industry Association of America (RIAA) introduced this warning label and it is now a requirement on any explicit music. However, the RIAA is unable to actually control whether or not adolescents will be listening to the music but as of now there is no way to fully control what these children are doing. Album covers in the age of downloads and streaming In August 2008, album cover designer Peter Saville suggested that the album cover was dead. Album art is still considered a vital part of the listening experience to many. Both MP3, WMA, M4A (Apple Format) music files are able to contain embedded digital album artworks (called cover images or simply covers) in jpeg format. One digital solution is the iTunes LP format for interactive album artwork introduced by Apple on 2009. Resolution for digital album covers should not be lower than 800x800 (1:1 Aspect Ratio), lower resolutions might not look good on newer devices. Some artists have used Internet technology to generate even more cover art. For instance, Nine Inch Nails initially released its album The Slip as a free download on the band's website, attaching separate but thematically connected images to each individual track. Banned covers Some album covers have been banned due to depicting violence, nudity, or other offensive imagery. For instance, Guns N' Roses's 1987 album Appetite for Destructions cover depicted a robot rapist about to be punished by a metal avenger, and Kanye West's 2010 album My Beautiful Dark Twisted Fantasy depicted West naked and being straddled by a phoenix with her bare breasts and buttocks showing.
