#' Shark Documentary Music
#'
#' Studies the effect of different kinds of background music on people watching shark documentaries.
#'
#' From the authors: "Despite the ongoing need for shark conservation and management, prevailing negative sentiments marginalize these animals and legitimize permissive exploitation. 
#' These negative attitudes arise from an instinctive, yet exaggerated fear, which is validated and reinforced by disproportionate and sensationalistic news coverage of shark ‘attacks’ 
#' and by highlighting shark-on-human violence in popular movies and documentaries. In this study, we investigate another subtler, yet powerful factor that contributes to this fear: 
#' the ominous background music that often accompanies shark footage in documentaries."
#'
#' The music in this experiment comes from https://open.spotify.com/album/7AQ9M23tA6AlBSsl7DocBJ. Ominous music is Track 9 1:45-2:45, while uplifting music is Track 1, 1:41-2:41.
