VH1 Fab life of, Common song help?

Hey again everyone, heres another hope of mine to try and find out a few song name used in this clip, if anyone can help or knows any lyrics i would be very appreciated.

YouTube - The Fabulous life of Britney and Kevin part 3

The first song i would like to know is the very first one in this clip after the theme song, and then if you move on to about 00:43 , i can hear the lyrics "who's bad?" but couldnt find anything else but jackson when searching on google. Then the final one is further along, at the time of 04:47. Any ideas?

Thanks. David G.

ok:

The first song is: Ying Yang Twins - "Salt Shaker".

00:43 is: Trina - "baddest *****".

04:47 is: Lil' Jon & The East Side Boyz - "I Don't Give A F***".



Now i realise ive heard another song in there i like... at 5:13 ?? Any ideas on that one, i cant belive i managed to find them three in a couple of hours.

Thanks
