A few days ago we released the first version of our new Metadata API and I wanted to make sure everyone knew about it. The Metadata API allows you to search for tracks, albums and artists, much like you search in the client, but you get the result in XML format.
The first use of the API was done on our very own http://www.spotify.com sharing links which, as of last week, display artists and track name rather than just the HTTP link when share with your friends.
Have a look at Magnus’ post on the developers site for all the details about the new API. We look forward to seeing all the neat uses that people come up with.
