So this `Source0` expands to https://github.com/leamas/spotify-make/archive/6237c6634340e49db233081e4afcc38ce3ebcecb/spotify-make-0.9.0.133.gd18ed58.259-6237c66.tar.gz which I can download fine, and manually placing it in `~/rpmbuild/SOURCES` allows `install-spotify` to proceed where previously it would cause:

However I'm curious why this `.../archive/...` URL works since I can't find it documented anywhere on github.  How did you discover it, and can it be relied on to stay?  The closest I can find which is documented is http://developer.github.com/v3/repos/contents/#get-archive-link ...
