LastHistory allows you to analyze music listening histories from through an interactive visualization and to explore your own past by combining the music you listened to with your own photos and calendar entries. It is written as a desktop application for Mac OS X v10.5 or higher.

LastHistory can be used in one of two modes, each of which is optimized for a different use case:

  • Analysis Mode
    This mode can be used for interactively analyzing an arbitrary listening history (not necessarily your own) in three basic dimensions: time, tracks and genre. Integrated tools like searching, playlist highlighting, mouse-over information, and zooming allow to generate insight for the visualized music listening history in each of those dimensions.
  • Personal Mode
    This mode adapts the visualization shown in Analysis mode for exploring your own past: by adding photos from your iPhoto library and calendar entries from iCal to the visualization, you can reminisce about your past by listening to the top tracks from your last vacation while watching a slide show of the corresponding photos. Or you can find the most influential tracks that you listened to most during a specific timeframe by inspecting the highlighted tracks in the visualization.

The application was created as part of my thesis (Diplomarbeit) at the Media Informatics Group of the University of Munich, supervised by Dominikus Baur.
