ViddyMP3 is primarily an audio book reader but is suitable as an MP3 player and audio-stream player for video files. All files are bookmarkable, and bookmarks may be auto-created by an import process. MP3 ID3v2 tag info is used extensively, and a sophisticated tag editor is included with all expected features, including rules-based mass renaming to/from tags/filename, tag record copy & paste, and auto-copying/sequencing abilities.
