the subject. Can anyone throw some light on the subject? TIA
	

Alright  matey  just a quick one I'm doing a short  film for my internet
site/showreel  and would like to put it to some music/ Audio... got some
tracks in mind that aren't mine do you know if  I'm aloud to use other
peoples tunes  without getting sued. I'm only thinking of around twenty
seconds of music  can you shed any light on the matter ??
