Does anybody know a simple remote control app that doesn't do anything more than control the Mac Mediakeys over wifi. I just want to control Spotify a little while it is playing on the big speakers. Don't have an IR remote. Don't want one either as it would only end up lying at places where it is no use. I can only find way more powerful remote control for Windows or the remote for iTunes but I don't do anything with iTunes. I got Spotify premium and have it on the iphone too but the iphone isn't connected to the speakers.
