So ... here is a silly thread...
I was just thinking about my forthcoming labour - the last one (my first) took ages, and hurt like hell - so I was thinking that I should make a play list to help get me through the next one (very much doubt I'll actually listen to it, but hey ho).
I always used to stuff my headphones in my ears and ramp up the volume when I went out running - it drowned out the sound of my own ragged breathing / impending melt down...
Any ideas? Here are a couple I just thought of:
Breathe don't stop - Mr. On Vs. Jungle Brothers
You can do it (put your ass in to it) - Ice Cube
