dbm does useful things with a library of music
The playlists and links can be used on a standalone digital music player such as an ipod, as long as it's running rockbox. For example, I use dbm to set up my ipod so that the main file menu looks like1
dbmwill need to be told); it's not something generated by
dbm relies on MusicBrainz identifiers to keep track of artists,
albums and tracks. That means that you will only get good results if a
fair proportion of your music library has been tagged in this way. Use
the MusicBrainz Picard tagger to add these identifiers to your music
Similarity between artists is based on data from the last.fm server. Here are the similar artist playlists it created for me. I will be adding the ability to define similarity by maintaining a personal spreadsheet file positioning each artist in some sort of 'music space' (This is currently implemented in R, but not yet in the python code that I'm distributing).
I'm still working on this; some of the features described above are in
more polished states than others. So at the moment it would make
sense to (a) make sure you've downloaded the latest version (>=
0.12), and (b) get in touch with me:
davison at stats dot ox dot ac dot uk. In fact, I'm basically looking for people to try it out
at the moment. And a better name.
dbm is written in python. It is available here.
dbm is a command-line program. Basically, you use the -i and -o
options to specify the locations of the input music library, and the
output folder. So to run dbm, open a terminal window (aka command
prompt), use the
cd command to move into the directory containing
dbm files, and enter something like
python dbm.py -i E:\Music -o dbm-output-folder
on Windows, which might look like this on linux:
python dbm.py -i /media/ipod/Music -o dbm-output-folder
This example tells
dbm to read a music library stored in a folder
called Music on an external drive (e.g. an ipod), and create a bunch
of output files and folders in a folder called
dbm-output-folder. This output folder will be created in whatever
folder you are in when you issue the command. If you've got a lot of
music, it'll take some time to read the library and make the
musicbrainz web queries for every artist. You'll get
some output to look at, but I can't recommend doing that for
dbm assumes artist music folders live in the
top level of the music library. Hopefully an example will make this
clear. Suppose that your music library is organised as follows:
dbm will work correctly if you use
-i E:\MusicFolders\AllMusic, but it will not work correctly with
-i E:\MusicFolders, nor with
If there are no major problems, the output directory will contain the following folders:
In addition, a file called
album_report.txt will be created. This
lists album folders that have tracks lacking the musicbrainz ID tags
dbm relies upon.
There are two extra options that you can use:
-mcheck for incomplete albums.
-nAt the end of every run, dbm saves database files in a hidden directory called ='.dbm'= in the output folder. This option tells
dbmto re-use those saved database files, rather than rescanning your music library, which can take a long time.
To use these extra options, just supply
-n in addition to
-o options, e.g.
./dbm.py -m -i /media/ipod/Music -o dbm-output-folder
If you run dbm without any options, or do something it doesn't understand, it will print out a help message like this
dbm version 0.10 Use -i and -o options to specify location of music library and output folder. E.g. ./dbm.py -i /media/ipod/music -o ~/music/ipod-dbm-output To additionally check for incomplete albums, use -m If you want to re-use saved database files in an existing output directory rather than scanning your music library again, use -n. To print this help message, use -h.
The playlist files are in the
.m3u format, and can be transferred
to an mp3 player which supports them. If you are not running rockbox
on your mp3 player then I strongly suggest investigating it.
