Mp3tag is a powerful and easy-to-use tool to edit metadata of audio files. Musicians, DJs, podcasters, and audio-enthusiasts use it for many different aspects of handling audio files.
It supports batch tag-editing for multiple files at once, covering many audio formats from MP3, over MP4, and M4V (yes, that's video!) to FLAC, OGG, OPUS, AIF, DSF, MPC, and WAV.
Furthermore, it supports online database lookups from Discogs and MusicBrainz, allowing to gather proper tags and download cover art for music libraries.
