I was able to go to http://developer.spotify.com, log in with my Spotify (premium) username/password, click "libspotify" in the top navigation, find "application key" (also in the top navigation) and then click c-code. Copy/paste this code into a text file and save as appkey.h, and you should be good to go.
It's been awhile since I've done this, and can't remember fully, but you may need to sign up for a developer's account. I'm sure others on this thread can confirm that.
Best of luck!
