Frontman Dave Mustaine recalled the writing of this song to Rolling Stone: "I was homeless at the time, and I was living in a rehearsal place in Vernon, California. I was seeing a girl, Diana — there were a lot of songs I wrote about her. I actually wrote the lyrics to that song on the wall, in that building. I didn't have any paper in the studio, but I had a Sharpie, so I just wrote on the wall. Whoever inherited our rehearsal room after I moved out, saw the original lyrics to 'Peace Sells' on the wall. They probably painted right over it and didn't even know it."
Mustaine also penned the opening bassline, which became famous for being used as the theme for MTV News. He told Rolling Stone that he never received any royalties for their usage of it. Said Mustaine: "They didn't give me a penny. They cut it off right before they'd have to pay me, which was very clever. I don't think anybody with a conscience at MTV did that — it was probably somebody in their legal department."
