I'm a little confused about exactly what you're trying to do, as play history is already stored in the database. What extra information are you wanting to store? It would be much more efficient for use the events such as "OnPlay" to trigger these updates, rather than have it looping continuously, although with a timer this would be possible.

I'd like to write a script that runs in the background all the time (to monitor what is being played). Is this possible with VBscripts?

Basically, it would collect information about what is playing and store this in the database. I can collect the info and store it, but not as a continuous background task.
