How do I batch edit the artist or album name of MP3 files on iPhone or Mac?

Import the MP3 files into Waketag, select the tracks that should share the same value and use batch editing for the relevant fields. Verify the selection before saving so an album artist or album name does not overwrite unrelated tracks. Keep copies of the originals and check one saved file in your usual player before continuing with a large library.

Steps to follow

1. Copy a small group of MP3 files and separate tracks that belong to different albums before selecting them.
2. Apply only the shared artist or album field; keep song titles and track numbers specific to each recording.
3. Save, reopen one edited file and inspect the same copy in the player you normally use.

Artist and album artist are not always identical

Compilations can contain different performers while sharing one album grouping. Review which field your player uses before standardizing a whole collection. If the test looks wrong, correct the small sample first rather than extending an uncertain batch operation to hundreds of files.
