Eminem’s 2000 song “Stan” is arguably one of the best songs featured on his classic album, The Marshall Mathers LP. The Detroit native recently annotated the LP and detailed some interesting factoids about the song.

Em went on Genius to explain his writing process on the chilling song. In one footnote, Slim Shady revealed that an original third verse was deleted because the engineer was stoned.

"When we recorded Stan I worked with a couple different engineers but this particular engineer I had never worked with before," he writes. "While we were recording the third verse of Stan, he started rolling a joint and asked me if I minded if he smoked while we cut. What was I gonna do? Say no? He was already rolling it so I told him 'no problem'."

"Back then we were recording on 2 inch tape, so once you recorded over something it’s gone forever," he continues. "So I’m in the booth waiting and he backs the tape up all the way to the beginning of the verse and punches me in. I realize he’s in the wrong spot and I can’t hear any of my vocals so I start waving my arms and yelling in the mic to try to get his attention. He doesn’t notice so I run into the control room through a cloud of smoke and yell 'Yo, I wanted to keep those vocals' he just looked at me and said 'My bad man...you wanna hit this?' The first half of the verse was GONE. I re-recorded it but you should have heard the original take that s--- was WAY better...oh well!"

Despite the engineer's snafu, Em's "Stan" remains a fan favorite in the rapper's extensive catalog and introduced a new word into the hip-hop lexicon.

Eminem also wrote about hearing the innovative beat from legendary producer Mark the 45 King. "[When] I first heard it, I was like, “Holy s---,” he wrote.
