13. Heads Will Roll — Yeah Yeah Yeahs (2009) — 13. Heads Will Roll — Yeah Yeah Yeahs (2009)

A dance-floor pulse and macabre title make this an efficient energy lift late in the set. It is more stylish than spooky, which helps prevent the playlist from becoming one-note.

The track earns its place through movement and tonal contrast, not through a claim that every part of it is Halloween-specific.
