NAME
    File::Find::Rule::MP3Info - rule to match on id3 tags, length, bitrate,
    etc

SYNOPSIS
      use File::Find::Rule::MP3Info;

      # Which mp3s haven't I set the artist tag on yet?
      my @mp3s = find( mp3info => { ARTIST => '' }, in => '/mp3' );

      # Or be OO.
      @mp3s = File::Find::Rule::MP3Info->file()
                                       ->mp3info( TITLE => 'Paper Bag' )
                                       ->in( '/mp3' );

      # What have I got that's 3 minutes or longer?
      @mp3s = File::Find::Rule::MP3Info->file()
                                       ->mp3info( MM => '>=3' )
                                       ->in( '/mp3' );

      # What have I got by either Kristin Hersh or Throwing Muses?
      # I'm sometimes lazy about case in my tags.
      @mp3s = find( mp3info =>
                        { ARTIST => qr/(kristin hersh|throwing muses)/i },
                    in => '/mp3' );

DESCRIPTION
    An interface between MP3::Info and File::Find::Rule to let you find
    files based on MP3-specific information such as bitrate, frequency,
    playing time, the stuff in the ID3 tag, and so on.

METHODS
  mp3info
      my @mp3s = find( mp3info => { YEAR => '1990' }, in => '/mp3' );

    Only matches when *all* criteria are met. You can be OO or procedural as
    you please, as per File::Find::Rule.

    The criteria you can use are those that are returned by the "get_mp3tag"
    and "get_mp3info" methods of MP3::Info.

    The following fields are treated as numeric and so can be matched
    against using Number::Compare comparisons: YEAR, BITRATE, FREQUENCY,
    SIZE, SECS, MM, SS, MS, FRAMES, FRAME_LENGTH, VBR_SCALE.

    The following fields are treated as strings and so can be matched
    against with either an exact match or a qr// regex: TITLE, ARTIST,
    ALBUM, COMMENT, GENRE.

    Anything else is matched against as an exact match.

    Let's make it DTRT with boolean fields, next!

    This needs benchmarking; will it be impossibly slow with lots of files?
    I'm seeing around a minute or so to go through 6 gig.

    Send me mail; it makes me happy. Does this suck? Why? Does it rock? Why?
