If you want a parser that you don't have to change when you change your set of input criteria, you can do something like the following:

use strict;
use warnings;
use Data::Dumper;


my %config = map { /^((?:inc|exc)_\w+)=(.*)$/ } <DATA>;
print Dumper(\%config);



__DATA__
inc_albums= a list of albums to include
inc_genres= a list of genres to include
inc_artists= a list of artists to include
inc_songs= a list of songs to include
inc_year= a list of years to include
exc_albums= a list of albums to exclude
exc_genres= a list of genres to exclude
exc_artists= a list of artists to exclude
exc_songs= a list of songs to exclude
exc_year= a list of years to exclude

Which gives:

$VAR1 = {
          'inc_genres' => ' a list of genres to include',
          'inc_year' => ' a list of years to include',
          'exc_albums' => ' a list of albums to exclude',
          'inc_albums' => ' a list of albums to include',
          'exc_year' => ' a list of years to exclude',
          'exc_songs' => ' a list of songs to exclude',
          'inc_artists' => ' a list of artists to include',
          'inc_songs' => ' a list of songs to include',
          'exc_artists' => ' a list of artists to exclude',
          'exc_genres' => ' a list of genres to exclude'
        };
