In my backyard, I have a left speaker on one end of my back wall and I have a right speake on the other end of that wall and there is about 30 ft. between them.  Unless I sit/stand right in the middle of the two speakers when I'm in backyard, music on Spotify will not sound good/natural because of the channel separation.  Would it be so hard for the Spotify dev. team to create a "mono" option in the settings panel?  This would seem like a no-brainer.  I see Spotify's users have been asking for this feature for a couple of years now, as far back as March of 2012 and then another 21 pgs. of comments following that.  I'm sure the hard of hearing community or people with a single speaker setup would appreciate this option too.  Come on Spotify!  Please listen to what your users are requesting and create a "mono" listening option for us!!!
