I mean, it says what the song is right on the screen. How long does it take to read that?

Well considering you're in a moving vehicle, maybe "too long?"

I dunno. I don't think it's a *superb* idea, but sometimes I'll have to look at my display a lot to tell what song is coming on, mainly if it's the kind of song that fades in or doesn't start off with anything discernable (ambient sounds, etc.) I've caught myself thinking it might be nice to have the artist/title announced, but I also think it might be annoying after awhile.

In any event, I am more interested in TTS for the trivia game, and pre-recorded TTS would seem to be a bad idea there.
