There seems to be a mismatch between the documentation of some of the return
types of the web API and the actual return types:
The docs for "get an albums tracks" says that it returns an album object. In reality it returns a paging object containing track objects.
The docs for "get-an-album" endpoints docs says that it returns an album object. It actually returns an object that looks like an album object, but where the "tracks" field is a paging object rather than an array
