Lala is available on the Python Package Index. This makes installing it with pip as easy as:
pip install mpd_pydb
If you want the latest code or even feel like contributing, the code is available on Github.
You can easily clone the code with git:
git clone git://github.com/mineo/mpd_pydb.git
Now you can start hacking on the code or install it system-wide:
python setup.py install
