Free mp3 database software for linux

Mr. Voice is a specific-purpose Perl/Tk front-end for an MP3 database.
It was written to provide an easy-to-use MP3 solution for the production booth of an improv comedy troupe, and as such is tailored to providing quick searches and playback of MP3s that are split up into categories.
While not intended to be a standalone desktop MP3 player, others in a similar situation may find it useful.
What is Mr. Voice? A way to have a ton of audio at your disposal, and to be able to call up just the clip you need, just when you need it. If youre running any sort of production that needs audio, such as improv shows, theatre, church events, that sort of thing, Mr. Voice can help. It handles a wide variety of audio formats (MP3, OGG, WAV, AAC, WMA), can do queueing and playlisting, and has a powerful SQL database backend (without needing the overhead of a big database engine like MySQL).
Plus, its 100% free and open-source.
What isnt Mr. Voice? A general-purpose MP3 player. In fact, it doesnt play audio at all by itself - it farms that off to an audio player like XMMS or WinAmp. Its also probably not a wonderful iTunes replacement. Sure, you can categorize and search audio files, but its not designed to become a jukebox.
Enhancements:
- A new option under the Online Preferences to edit the XML-RPC (Mr. Voice Online) URL that is used (in case I need to change it again). It was hardcoded into the program before.
- Fixed bugs that were causing strange quote marks to appear in song and category names.
- Display the song filename in the "Edit Song" menu. Suggested by Bill in Portland.
- Display the time of a song next to the hotkey listing. Suggested by Ted in Chapel Hill.
- Added an option under the File menu to export the song list from your Mr. Voice database as either a text file or Microsoft Excel spreadsheet. Suggested by Ted in Chapel Hill.

AnyData::Format::Mp3 is a tied hash and DBI access to Mp3 files.

SYNOPSIS

use AnyData;
my $playlist = adTie( Passwd, [c:/My Music/] );
while (my $song = each %$playlist){
print $song->{artist} if $song->{genre} eq Reggae
}

OR

use DBI
my $dbh = DBI->connect(dbi:AnyData:);
$dbh->func(playlist,Mp3,[c:/My Music],ad_catalog);
my $playlist = $dbh->selectall_arrayref( qq{
SELECT artist, title FROM playlist WHERE genre = Reggae
});
# ... other DBI/SQL operations

This module provides a tied hash interface and a DBI/SQL interface to MP files. It creates an in-memory database or hash from the Mp3 files themselves without actually creating a separate database file. This means that the database is automatically updated just by moving files in or out of the directories.
Many mp3 (mpeg three) music files contain a header describing the song name, artist, and other information about the music.

Simply choose Mp3 as the format and give a reference to an array of directories containing mp3 files. Each file in those directories will become a record containing the fields:

song
artist
album
year
genre
filename
filesize

This module is a submodule of the AnyData.pm and DBD::AnyData.pm modules. Refer to their documentation for further details.
