OK, let's try to correct the code first, I'll explain the code after that.

Try this:

Code:

find . -type f -name '*.[Mm][Pp]3' -exec id3 -Rl {} + -o \
  -name '*.[Ff][Ll][Aa][Cc]' -exec metaflac --show-md5sum  \
    --with-filename --export-tags-to=- {} + |
  awk 'BEGIN {
    mp3n        = split("album artist title track",       mp3_tags)
    flacn       = split("album artist title tracknumber", flac_tags)
    ignorepatt  = "^ *(unknown|track *[0-9]*)* *$"    
    }
  /^Filename/ || $1 ~ /\.[Ff][Ll][Aa][Cc]$/ {
    if (fn) {
      if (fn ~ /\.[Ff][Ll][Aa][Cc]$/) {
        for (i = 1; i <= flacn; i++) {
          if (tolower(tags[flac_tags[i]]) ~ ignorepatt) {
            invalid_tags[flac_tags[i]] = tags[flac_tags[i]]
            f || f++
            }
          }
        if (f) {
          print RS, fn, "has missing/invalid tags:"
          for (t in invalid_tags)
            printf "%s -> %s\n", t, invalid_tags[t]
            }      
          }    
     else { 
       for (i = 1; i <= mp3n; i++) {
         if (tolower(tags[mp3_tags[i]]) ~ ignorepatt) {
           invalid_tags[mp3_tags[i]] = tags[mp3_tags[i]]
           f || f++
             }
           }
       if (f) {
         print RS, fn, "has missing/invalid tags:"
         for (t in invalid_tags)
           printf "%s -> %s\n", t, invalid_tags[t]
          } 
        }
      }
    split(x, tags); split(x, invalid_tags)
    fn = /^Filename/ ? $2 : $1; f = x        
     }
 { 
    if (split($0, tmp, "=") == 2) {
      $1 = tmp[1]; $2 = tmp[2]
      }
    tags[tolower($1)] = $2
    }
  END {
       if (fn ~ /\.[Ff][Ll][Aa][Cc]$/) {
        for (i = 1; i <= flacn; i++) {
          if (tolower(tags[flac_tags[i]]) ~ ignorepatt) {
            invalid_tags[flac_tags[i]] = tags[flac_tags[i]]
            f || f++
            }
          }
       if (f) {
         print RS, fn, "has missing/invalid tags:"
         for (t in invalid_tags)
           printf "%s -> %s\n", t, invalid_tags[t]
          }      
        }    
    else  
      for (i = 1; i <= mp3n; i++) {
        if (tolower(tags[mp3_tags[i]]) ~ ignorepatt) {
          invalid_tags[mp3_tags[i]] = tags[mp3_tags[i]]
          f || f++
          }
        }
      if (f) {
       print RS, fn, "has missing/invalid tags:"
        for (t in invalid_tags)
          printf "%s -> %s\n", t, invalid_tags[t]
        }      
      }' FS=:

audio::mpd::common::item::song

Audio::MPD::Common::Item::Song(3pm)			User Contributed Perl Documentation		       Audio::MPD::Common::Item::Song(3pm)

NAME

       Audio::MPD::Common::Item::Song - a song object with some audio tags

VERSION

       version 1.120881

DESCRIPTION

       Audio::MPD::Common::Item::Song is more a placeholder with some attributes. Those attributes are taken from the song tags, so some of them
       can be empty depending on the file.

       The constructor should only be called by Audio::MPD::Common::Item's constructor.

ATTRIBUTES

   album
       Album of the song. (format code: %d)

   artist
       Artist of the song. (format code: %a)

   albumartist
       Artist of the album. (format code: %A)

   composer
       Song composer. (format code: %C)

   date
       Last modification date of the song. (format code: %M)

   disc
       Disc number of the album. This is a string to allow tags such as "1/2".	(format code: %D)

   file
       Path to the song. Only attribute which will always be defined. (format code: %f)

   genre
       Genre of the song. (format code: %g)

   id
       Id of the song in MPD's database. (format code: %i)

   last_modified
       Last time the song was modified. (format code: %m)

   name
       Name of the song (for http streams). (format code: %N)

   performer
       Song performer. (format code: %P)

   pos
       Position of the song in the playlist. (format code: %p)

   title
       Title of the song. (format code: %t)

   track
       Track number of the song. (format code: %n)

   time
       Length of the song in seconds. (format code: %l)

METHODS

   as_string
	   my $str = $song->as_string( [$format] );

       Return a string representing $song. If $format is specified, use it to format the string. Otherwise, the string returned will be:

       either "album = track = artist = title"
       or "artist = title"
       or "title"
       or "file"

       (in this order), depending on the existing tags of the song. The last possibility always exist of course, since it's a path.

       This method is also used to automatically stringify the $song.

       WARNING: the format codes are not yet definitive and may be subject to change!
