Decibel aims to be a straight forward simple audio player and, as such, it does not include features that are not necessary. Features such as tagging are left out as the are best suited for specialized audio management software. If you're looking for an audio player than can also make coffee, then you should stay away from Decibel and give a try to other players (e.g., Amarok, Exaile).
