I’m a newbie. I wanna make a site but don’t which niche I can get more revenue?

Dear DP Folks,
I am a newbie to this industry. I am thinking of making a site but I can’t think a good niche. I have some ideas:
1. Music site
2. Movie site
3. Flash game site
4. Artists Review Blog
5. Pornography ( Sorry, I want it also)
6. Tutorials on Computer Graphic Design
7. Others (Your suggestion)
So I really need help from you guys. Which niche is really good? Which Ad company is good for the niche? (I have no problem with technique things – web and hosting)
Looking forward to hearing from you guys.
Regards,
