Take it off of silent when you put headphones on. All sounds will route to headphones then anyway. Just remember to go back to silent if you stop using headphones.
I can think of a great reason for wanting uninterrupted music. Where I work we have a stereo with an eighth inch jack that we can hook MP3 players up to. We use this to play music for the entire store. I really like the idea of hooking my Droid up so that we can all listen to Pandora, but it will be very jarring for us and the customers if it stops the music every time a call or text etc. comes in. I'm disappointed that neither the Droid OS nor the Pandora app allow for uninterrupted music. I'm also a gigging musician, and it would be great to play Pandora through the PA before the show starts, but once again, interruptions will make it sound very unprofessional, and that's a shame. If anyone comes up with a workaround that doesn't include rooting my Droid, I'd be very happy to hear it.
