Last.fm to Twitter

Description: 

PHP script to post what your listening to to Twitter. It will only post the album when it changes.

Due to the last.fm api it's a bit ropey because the results are inconsistent. The twitter code was taken from the twitter api examples.

You'll need a twitter api key a Last.fm account. You can follow me on twitter @digital_mike
