Retrieving album artist info from third party API
Some pointers:


Move $http.get out of the controller to a service. Stuff that is not presentation logic should not be in your controller.
getAlbums should probably be a method of the controller and not the $scope , see this video on egghead.io on how to use controller as syntax.
I don't really see the point in your ng-if="albums.length &gt; 0". Why is it there?
It's common practice to postfix your controllers - so AlbumController or AlbumCtrl are more common names. I usually try to stick to conventions like this to convey intent more clearly.
If you're considering minification - consider using the minification syntax - start by reading this.
