This is my personal media library which I wrote after being frustrated with other solutions which use pre-1970s database technology.
The feature-set is mostly geared towards accurately storing western classical music circa 1500 to the present day. It also supports albums ("non-classical") too with correct support for multiple CDs.
It is entirely web-based and generates XSPF files pointing to the actual files.
Local database setup
Create PostgreSQL user with id matching your UNIX username:
$ sudo -u postgres createuser $(whoami) -SDR
Create a database owned by this user:
$ sudo -u postgres createdb -E UTF-8 -O $(whoami) musicdb
Check we can connect to this database:
$ /usr/bin/psql musicdb psql (9.1.2) Type "help" for help. musicdb=> \q
Syncing with the live site (lamby only)
$ ./manage.py sync_database
