So I've just recently switched from a 3gs to a galaxy nexus and am loving the phone. The only issue that has prevented me from not using my 3gs totally is the music playback. Though google music works well in porting my songs/playlists from iTunes, my inline controls on my headphones do not appear to work. I am able to play/pause music and skip a track, but I am unable to use the volume buttons nor rewind a track. Is this an android issue or ICS? Or is it a headphones thing? If it helps, I am using klipsch image S4.
