The Player That Fixes Your Library.
Legendary MP3 plays the music already on your phone, repairs its tags against MusicBrainz, fetches missing cover art, and measures tempo and key from the audio. No account, no ads, no analytics.
What It Does
Fix
Library Health reads every file and finds the missing tags, split artists and bare covers. Fixes come from MusicBrainz, and you approve each one before it is written.
Hear
The app listens to each song once and measures tempo, key and energy from the audio. "More at this tempo" and key-matched playlists come from that, not from a tag.
Play
Gapless, crossfade, an equalizer, ReplayGain, visualizers, lyrics, three styles, scrobbling to Last.fm and ListenBrainz. All of it free.
