I meant that you likely need to ->configure your tag writer, because that is where write_v24 needs to be enabled so that it is allowed later on. But then, that's only how I interpret the documentation - I haven't used the module.

You are a champion, I've never used "configure" in a library before and I assumed it handled in the function not a global config item. Thanks so much.

MP3::Tag->config(write_v24 => 1);

fixed it and it ran perfectly. full code now is:

#!/usr/bin/perl
use strict;
use warnings;
use MP3::Tag;
MP3::Tag->config(write_v24 => 1);

$mp3->title_set('new title');
$mp3->update_tags();
$mp3 = MP3::Tag->new($file);
($title, $track, $artist, $album, $comment, $year, $genre) = $mp3->aut
+oinfo();
print("$title, $track, $artist, $album, $comment, $year, $genre\n");
