autoload seems inconsistent

[Stefan Huchler]

I am the author of kodi-remote which is in melpa.

When I manually evaluate the whole kodi-remote.el file all works
fine. But when I install it over melpa and it autoloads something goes
south.

When I start kodi-remote-movies it works but if I open up
kodi-remote-series or kodi-remote or kodi-remote-music I get such
errors:

"kodi-remote-music-mode symbol value as variable is void"

Here is the file:

https://github.com/spiderbit/kodi-remote.el/blob/master/kodi-remote.el

did I fuck up something with the autoload directive, can't figure out
what the problem is.
