sing along

Why has no one told me how much better it is running with music?!  I got some amazing wooly earmuff headphones for christmas and finaly got round to testing them out this morning, they were brilliant.  It was so windy today and they kept my ears nice and snug whilst amusing me with some lovely tunes.  I'd always been scared I wouldn't be able to hear the car that was about to run me over if I ran around Sheffield with headphones on but glady that didn't pose a problem...  I'm officially a convert.  So I need some new tunes, mellow accoustic stuff is not helping me get faster and neither is the fact that I just can't help but try and sing along, which a) makes me look mental, and b) means I cant breathe
