"Stan" is the third single from the The Marshall Mathers LP, recorded in 1999 by Eminem featuring British singer Dido. The song tells the story of a fictitious person named Stanley "Stan" Mitchell who claims to be the biggest fan of Eminem (In the album, Eminem uses his alter ego, Slim Shady). In the song, he writes letters to Eminem, with each verse he becomes gradually more obsessed with him, and when there is no reply he becomes progressively angrier.
