Levi's mum,
Music can be wonderful during labour. Many women find it really helpful - me included!
I tried music with words during my first labour and found it too distracting (when in full on labour). However, I found some instrumental music really fantastic. I listened to chants during Eva's birth and I found it wonderful. Afterward she always slept when it was on.

I can offer some cd titles if you would like - however, music can be a very personal thing. What one finds soothing can drive another batty!
