Subject: [PATCH 5/5] Fix track georestriction and add playable_tracks to
struct album_browse
The despotify library already marks georestricted tracks as unplayable in
despotify_get_tracks() but doesn't do this in despotify_get_album(), leading
to hung connections when playing albums containing georestricted tracks. As
well as fixing this, we add a count of playable tracks to struct album_browse
so album listings can conveniently identify albums containing unplayable
tracks.

arachsys commented Jun 16, 2012

I use the Despotify lib/*.[ch] library files directly in my own (private) Spotify command line client, and as well as some modifications which aren't suitable for upstream, I've accumulated these fixes which are more generally applicable. I'd love to contribute them back to Despotify, but I've completely failed to contact the upstream maintainers. The Sourceforge project appears to be dead, as does #despotify on EFnet.
