Janet Jackson/YMMV

Best Known for the Fanservice: Her scandal at the 2004 Super Bowl drew more attention afterwards than the actual game.
Growing the Beard: Control, her third album, was where she found her voice.
Jumping the Shark: Many of her fans miss the old days when she focused on writing music with a good beat instead of extremely sexual lyrics.
Never Live It Down: Her "Wardrobe Malfunction" at the 2004 Super Bowl.
No Such Thing as Bad Publicity: One theory was that the "malfunction" mentioned above was a deliberate attempt on her part to invoke this trope.
