Vux is a command-line ogg and mp3 utility that plays songs according to a rating system designed to keep track of user listening habits. by default, vux will give each song a percent chance of playing, based on where it lies on a bell curve of all ratings. songs are picked at random, then played if they pass the percent chance. ratings increase when you play complete songs and decrease when you skip them. the ratings scorelist is plain text for manual editing. by default, a separate agelist is maintained to prevent repeats based on time since last played.
