Anyone fitting this description would be more of the mind "I might even consider partnering up with you." The world is sort of your oyster right now if you can do that. If you ask the kind of person you need what their next best alternative is, you will not hear "I got offered 5% equity and all the cola I can drink from an unfunded startup and am pretty darn tempted by that."

The traditional way to get traction for music sites and video sites is to turn a blind eye to folks stealing things that the established players can't turn a blind eye to. This lets you perform, essentially, visibility/legal-risk arbitrage. That's the on-the-ground reality, I personally wouldn't endorse acting on it.

You then use your early adopters to promote it to their friends, focusing feature development resources on implementing and optimizing things about the site which encourage social spreading rather than ones which merely encourage passive consumption.
