The Mp3tag Alternative With Audio Intelligence Built In.
Mp3tag edits the tags you already have. CrateDigger figures out what the tags should be.
The core difference
Mp3tag is a rock-solid batch tag editor that's been around since 2000. But it was designed for album collectors who manually curate metadata. DJs need their tracks identified and analyzed automatically — BPM, key, clean/explicit — not just edited.
