• "Obsessica" is Malcolm Todd's confession about the thrill and absurdity of obsession. Rather than treating infatuation as a tragic affliction, Todd examines it in real time, documenting the cycle of falling, spiralling, recovering, and then diving straight back in again. By the song's closing moments, an increasingly long list of names reveals that the fixation has outgrown any one person. The real object of desire isn't Rebecca, Stacy, Macy, Tracy, or anyone else; it's the feeling of obsession itself.
• The title is almost certainly a portmanteau of "obsess" and "Rebecca," one of the names Todd rattles off during the outro. It's a joke, but it's also a clever piece of songwriting. By merging the condition with a person's name, Todd suggests that the obsession and its target have become impossible to separate. By the end of the song, the list has become so extensive that it resembles a school register being called by someone who has misplaced their emotional boundaries.
• "Obsessica" appears on Do It Again, Malcom Todd's second album. The record was written and recorded over six months at Electric Lady Studios in New York and Chaplin Recording Studios in Los Angeles during a summer when Todd found himself newly single. That experience informs many of the album's recurring themes of attraction, longing, uncertainty, and emotional contradiction. While "I Saw Your Face" explores the guilt and sadness of ending a relationship, "Obsessica" captures what happens next, when the mind starts filling the empty space with an endless parade of possibilities, fantasies, and questionable decisions.
• Todd wrote the song with Charlie Ziman, Jonah Cochran, Jasper Harris, Matthew Castellanos, and Jackson Tracy. The track was co-produced by Todd, Ziman, Cochran, Harris, and Castellanos, while Tracy served as recording engineer.
  
  This larger group marks a shift for Todd. While earlier fan favorites like"Earrings" and "Chest Pain (I Love)" grew out of a tight-knit circle - typically just Todd, Cochran, and Ziman - Do It Again saw him widen the net.
