Cheers for the feedback.

Right at the moment the code isn't exactly brilliant, this is a rough first attempt at getting something up and running. In theory it should be pretty easy to use multiple sources. I just need to write some sort of parser to get all the data into a consistent format.

My original idea was to have multiple sources for gigs. Last.fm is the source I was familiar with so I started with that, I'll look into the sources you mentioned.
