Muting music drives me crazy. I never turn music off, stream it into my headset via bluetooth whenever I'm flying. I just set the intercom and radio volume above the music and have no problem seperating the two or getting distracted.
I definitely agree with this. I flew in solid IMC for about an hour a couple weeks ago, music the entire time. I always fly with music and I never mute it. I've taken checkrides with music on too and it's never been an issue.
