First of all, I'm not sure I understand how your web application
interacts with Banshee.
If it's connecting directly to the sqlite database, it might not be a
good idea, especially if Banshee is running at the same time :
accessing an sqlite database file from multiple processes can lead to
corruption.

I think what you're trying to achieve can be done using the various
d-bus interfaces provided by Banshee. In particular, the
org.bansheeproject.Banshee.PlayQueue has an EnqueueUri method that
adds a track to the playqueue, with its URL as a parameter.
You can try it with a d-bus tool like dbus-explorer.
Bonus tip for manual tests : you have to replace space by "%20" in the
URL, for example : file:///path/to/Some%20Name.mp3

Don't hesitate to ask if you have other questions.
