I am on Arch Linux and downloaded the spotify package from the AUR. Most of the usual Windows keybindings do not work (e.g. Ctrl + right/left for next/prev track, Ctrl + up/down for increase/decrease volume) although there are some keybindings that *do* seem to do what they're supposed to (Ctrl + s to shuffle, Shift + right/left to fast forward/rewind).
I do not think this is an issue with spotify keybindings conflicting with my window manager keybindings.
