As far as many clients are concerned, nowadays (especially the younger ones), a DJ and a musician ARE both 'live music'!

I guess that is to distinguish it from them just hooking up their own iPod's and spinning what they feel like.

Personally, I make sure the client (not the agent!) knows EXACTLY what I do (and don't do) before every single gig. I don't need the work so bad that I am prepared to stand by a laptop and DJ... I actually like PLAYING more than I like money...
