There is an empty list under youtube-dl https://music.yandex.ru/album/1456657

It gives another Type Error now:

  File "/usr/lib64/python2.7/site-packages/youtube_dl/extractor/yandexmusic.py", line 88, in _get_track_url
    % (data['host'], key, data['ts'] + data['path'], storage[1]))
TypeError: unsupported operand type(s) for +: 'NoneType' and 'unicode'

I tried to reproduce the error and inserted debugging print() class, but suddenly all become nice again.
