Invoking cover_link() on an Album object yields the following run-time error:
File "/usr/local/lib/python2.7/dist-packages/spotify/album.py", line 112, in cover_link
File "/usr/local/lib/python2.7/dist-packages/spotify/__init__.py", line 44, in wrapper
return f(*args, **kwargs)
TypeError: an integer is required
I think this might be caused by passing spotify.ImageSize.NORMAL as an integer.
Fix flipped logic in Album.cover_link (fixes #126)
Thanks for your bug report! The issue should be fixed in the develop branch now. A 2.0.0b1 release should hopefully only be a week or so away if you want to wait for a new release.
