First, the writers talked about the emotional issues facing Buffy Summers and how she would confront them through her battle against evil supernatural forces. Then the episode's story was "broken" into acts and scenes. Act breaks were designed as key moments to intrigue viewers so that they would stay with the episode following the commercial break. The writers collectively filled in scenes surrounding these act breaks for a more fleshed-out story. A whiteboard marked their progress by mapping brief descriptions of each scene. Once "breaking" was done, the credited author wrote an outline for the episode, which was checked by Whedon or Noxon. The writer then wrote a full script, which went through a series of drafts, and finally a quick rewrite from the showrunner. The final article was used as the shooting script. Music Buffy features a mix of original, indie, rock, and pop music. The composers spent around seven days scoring between fourteen and thirty minutes of music for each episode. Christophe Beck revealed that the Buffy composers used computers and synthesizers and were limited to recording one or two "real" samples. Despite this, their goal was to produce "dramatic" orchestration that would stand up to film scores. Alongside the score, most episodes featured indie rock music, usually at the characters' venue of choice, The Bronze. Buffy music supervisor John King explained that "we like to use unsigned bands" that "you would believe would play in this place". For example, the fictional group Dingoes Ate My Baby were portrayed on screen by front group Four Star Mary. Pop songs by famous artists were rarely featured prominently, but several episodes spotlighted the sounds of more famous artists such as Sarah McLachlan, The Brian Jonestown Massacre, Blink-182, Third Eye Blind, Aimee Mann (who also had a line of dialogue), The Dandy Warhols, Cibo Matto, Coldplay, Lisa Loeb, K's Choice, and Michelle Branch. The popularity of music used in Buffy has led to the release of four soundtrack albums: Buffy
