Oh wow. Ok thanks. I had no idea there was a legal issue around lyrics... My Synology has an official plugin for the DS audio app that just gets them so I assumed it was a pretty normal thing to do.
I dont really understand why my Synology wont play back to my preamp's asynchronous USB input anyway. JRiver on the PC plays back on it just fine, and the Synology "sees" the USB dac chip, but nothing plays.
