Reply to Where to buy music video's.

I have some gigs coming up where I will be playing music video's and need to expand my collection. I know I can buy video's from iTunes (and have in the past) but they are $1.99 each which will add up quick. Does anyone know of another place I can get music video's legally? I am looking for Top40 (old & new) and some commercial EDM would be nice to mix in as well.
