Sight reading generally refers to playing a song for the first time, in which case, you may as well be playing with the sound off. It does not, I don't think, count for if you play on random (unless it's your first time playing the song, and you happen to have on Random).
What Pepe said is something I've never personally heard for sight read, and I think there's another term for when the notes just don't [obviously] follow the song.
On a different note, sometimes I find my timing is better when the sound is off. |
