A minimal OS X iTunes scrobbling solution that implements Audioscrobbler protocol 2.0.

To compile it you'll need to create lastfm_api.h and add a Last.fm key and secret like so:

  #define LASTFM_API_KEY       "abcdef0123456789abcdef0123456789"
  #define LASTFM_SHARED_SECRET "abcdef0123456789abcdef0123456789"
