I am breaking out in a sweat just looking at all that work you did for such a simple single-table commit to database. Have a look at a SQL::Catalog + DBIx version of the same code 

package DBH;

use strict;
use DBIx;

use constant DBI_DSN  => 'DBI:vendor:database:host';
use constant DBI_USER => 'user';
use constant DBI_PASS => 'pass';
my $DBH;

sub import {
   unless (ref $DBH) {
      $DBH = DBI->connect(
         DBI_DSN, DBI_USER, DBI_PASS,
         {RaiseError => 1}
      );
   }
   $DBIx::DBH = $DBH;
}

1;
package main;

use DBH; # creates database handle via import()

### initialize + config code un-necessary
### not with SQL::Catalog + DBIx
### and not, as mentioned in the conclusion
### with DBIx::Recordset
### and probably not Alzabo either



find sub {
   return unless m/\.mp3$/;
   
   my $tag = get_mp3tag($_) or return;
   my %tag = %$tag;
    # sql_do finds the $dbh for you...
    sql_do sql_lookup 'insert_mp3_tag_data', 
         @tag{title artist album year genre} ;
 
}, @ARGV;

Also, consider that your entire example would be a DBIx::Recordset one-liner. I think I will contact Dave Rolsky and coax him into posting an Alzabo version. Then every person who is actively working on database frameworks will have an example here.
