Can the finder edit mp3 sound file tags like artist?
For those seeking a free terminal-based solution


Per the rest of the answerers in here, Finder (as of El Capitan) does not do this.
I arrived at id3v2 referenced in a Linux forum.


Installation


  Via HomeBrew - Update HomeBrew and install commands


brew update &amp;&amp; brew install id3v2


Example Usage

Change Artist to Prince

id3v2 -a "Prince" 01\ Wow.mp3


Change Title to Wow

id3v2 -t "Wow" 01\ Wow.mp3
