So here is how to make all your apps (at least in gnome) open spotify url’s.

First of all create the browser2spotify script that’s going to be called when you click on a spotify link, don’t forget to make it executable!

echo ‘#!/bin/sh’ > ~/.browser2spotify
echo ‘exec wine “C:\Program Files\Spotify\spotify.exe” /uri “$@”‘ >> ~/.browser2spotify
chmod 755 ~/.browser2spotify

Now let’s associate spotify URL with the open script by editing gconf. Change USERNAME for your account login name

gconftool-2 -t string -s /desktop/gnome/url-handlers/spotify/command “/home/USERNAME/.browser2spotify”
gconftool-2 -s /desktop/gnome/url-handlers/spotify/needs_terminal false -t bool
gconftool-2 -s /desktop/gnome/url-handlers/spotify/enabled true -t bool

You should now be set and ready to roll.
