Music means a lot to me, even when I'm not listening to music there's some song stuck in my head, I knit a lot to music (usually when I'm home alone) and knit to the tv when someone else is around. I find it's a lot easier to tune out the tv and I find myself having to count stitches when I'm listening to music 'cause I get distracted (singing and dancing with my cats, usually. they love it... really.)
But I have to say, sometimes it's nice to knit with nothing else going on and just give yourself to what's going on in your hands (this works really well if I'm stressed about school, doesn't take long until I've calmed down).
Just my two cents,
