The document discusses the process of selecting a cover version of the song "Demons" by Imagine Dragons to use as the non-diegetic soundtrack for a trailer. The group evaluated several YouTube covers but ultimately decided on the version by Tanner Howe due to qualities like the haunting piano introduction, balance of vocals and music, and clarity of lyrics. They reached out to Tanner Howe for permission to use the cover but did not receive a reply, so had a backup plan to use a cover by Heart & Heads if needed.
