Fix your music's tags, covers and lyrics. On your device, without losing a thing.
- Edit every tag: title, artists, album, album artists, year, genres, track and disc numbers, credits, comment, BPM, ISRC, lyrics, and any other tag in the file under All tags.
- Never lose data: Metadator writes only what you changed, keeps every other tag and picture, and backs the file up first. Every save can be undone.
- Find metadata online: search MusicBrainz and Deezer at once, compare each field with what the song has, and pick what to use. Covers up to 1200 px.
- Lyrics: find plain or synced lyrics on LRCLIB.
- Edit many songs at once: set an album artist or a cover for a whole album, number tracks, read tags from file names.
- A library that shows what to fix: search everything, sort, filter by format, and see which songs are missing tags.
- A simple music player, with background playback and the system's media controls.
- Open with Metadator from any file manager or player, no library permission needed.
- Material 3 Expressive, with colors from your wallpaper or the song's cover, and a two-pane layout on tablets and foldables.
Supported formats: everything TagLib reads, including MP3, FLAC, M4A/AAC/ALAC, Ogg Vorbis, Opus, WAV, AIFF, WMA and APE.
Metadator works on your device. The only thing that leaves it is a song's title, artist and album when you search for metadata or lyrics, sent to the source you search. The Google Play build sends anonymous crash reports; the FOSS build sends nothing.
Requirements: JDK 21 and the Android SDK (compile SDK 37).
