It appears that the libspotify page is once again no longer able to generate application keys. When trying, either via Firefox or Internet Explorer, the page reports that "There was an error generating your application key". Is the site down again, or am I doing something wrong? I've never used that page before.
Earlier today, the SpotifyPlatform Twitter account reported that the service is having issues. However, they must either be working on it or have finished doing so as a key request I just put in worked properly.
