Thank you Supasta. That's just what I needed. Although I did come up with a workaround on my own. My TV allows me to program and save a "Custom" screen setting, so I created one with the screen so dark you can just barely read the song information. So when the lights are out and the romantic music is playing, that bright grey default Tivo screen won't spoil the mood!
But I will give Audiofaucet a try too.
