Technical features.
Zinf can play sound files in MP3, Vorbis, and WAV formats, among others. It supports skins and is part of the MusicBrainz network. The player features an optimized version of the Xing MPEG decoder, a powerful music browser and playlist editor, and a built in
download manager which supports downloading files from sites using the RMP (RealJukebox) download process. Zinf was also notable for handling all audio files based on their metadata (Author, Album, Song Title), and hiding more-technical details like actual locations and file names (but these features are now standard in many players).
Naming.
Zinf is a recursive acronym that stands for "Zinf Is Not FreeAmp!" Use of the name FreeAmp had to be discontinued due to trademark issues, as "AMP"
