Kid3 is a free opensource tool to easily tag multiple MP3 files (e.g. full albums) without typing the same information again and again and allow you to control and edit ID3v1 and ID3v2 tags. It’s one of those things I started doing so enthusiatically and then give up after a few tracks and finally this should help me get around this.
Kid3 features include,
Edit ID3v1.1 tags and all ID3v2.3 and ID3v2.4 frames
Convert between ID3v1.1, ID3v2.3 and ID3v2.4 tags
Edit tags in MP3, Ogg/Vorbis, FLAC, MPC, MP4/AAC, MP2, Speex, TrueAudio and WavPack files
Edit tags like artist,album,year,genre etc of multiple files with same value
Generate tags from filenames and vice versa
Rename and create directories from tags
Generate playlist files
Automatically convert upper and lower case and replace strings
Import album data from gnudb.org, TrackType.org, MusicBrainz, Discogs and other sources
Export tags as CSV, HTML, playlists, Kover XML and in other formats
