I would say get used to playing with your palm lightly touching the strings. This allows you to get that cool muted sound when you want, let off when you want the notes to ring out, and immediately place your palm back on the strings to mute the guitar when you are not actively playing or there is a rest between notes. This is good playing technique anyway. You should be practicing muting any strings that you are not playing anyway. Also, if you watch professional guitarists play live, especially if they are playing single coil guitars, they turn the volume all the way down between songs and turn it back up when starting the next song. The reason for this is because nobody wants to listen to the hum between songs.
