I have:

  1. A wife that doesn't want to use the TV to browse music.
  2. A Synology DS211, though I'm considering upgrading to a 4-bay model soon.
  3. A standard amplifier.

How can #1 get music from #2 to #3?

She might -- provided it allows her to browse, rather than search -- be persuaded to use a tablet to find music. I have a spare RPi that I can plug into the amp, if necessary.

Is the Synology software usable? Does Plex work? And by "work", I mean: "work without messing around with the configuration every time I want to change anything".

It'd be nice if the kids (4 and 6) could use this, too.

To be honest, I'd like some kind of kiosk mode for the tablet, though that might be another question.

And, by tablet, I'm basically talking about a Nexus 7 or an iPad mini.
