[http://gjay.sourceforge.net/ GJay] generates playlists across a collection of music (ogg, mp3, wav) such that each song sounds good following the previous song. It is ideal for home users who want a non-random way to wander large collections or for DJs planning a set list. You can generate playlists from within the application, or run GJay as a standalone command-line utility.
Playlist matches are based on:
- Song characteristics that don't change
- Frequency fingerprint
- Beats per minute
- Location in file system
- Song attributes that you set
- Rating
- Color (whatever that means to you)
sudo apt-get install gjay vorbis-tools
This will install also ogg suport
