What would be a good list of songs for a 13-year-old's dance- themed birthday party?

I'm turning 13 and I finally convinced my parents to let me have a dance party for my birthday. The thing is they say it has to be at my house, I'm not allowed to rent catering, a dance floor, or a DJ. At the moment I am trying to address the music issue.... I need at least 3 hours- worth of hip hop, and the occasional slow songs. Some of the music we listen too includes Rihanna, Chris Brown, T.I., Taylor Swift, Snow Patrol, Kelly Clarkson, Britney Spears, Will Smith, Flo Rida, etc. I need GOOD music. Please if you are putting inappropriate songs on the list, please write next to them "(swearing)" or "(inappropriate)" so I know. Please, good answers!!! 3 hours is like, 45 songs. I need as many as possible since my parents are giving me an iTunes card to spend. :):) Thanks
