Whether or not we believe in the concept of guilty musical pleasures, most of us enjoy a few songs and artists that we'd rather not be caught listening to -- and rock's biggest acts are no different, as evidenced by a recent Fuse piece that asked famous rockers to share the darkest secrets of their personal playlists.

Several hard rock artists weighed in on their guilty pleasure pop songs, including Slash, Marilyn Manson, Ministry frontman Al Jourgensen, Alice Cooper, and Evanescence's Amy Lee.

Slash is apparently a sucker for Katy Perry's 'California Gurls,' while Marilyn Manson digs Justin Timberlake's 'Cry Me a River.' Check out what other rockers had to say in the video below and let us know what you think -- are these pleasures worth feeling guilty about? How many do you share, and which songs and artists would make your list?
