a song in a dance video

YouTube - future shock san jose

thats the link...umm...i just wanna know the names of these songs...especially the beginning 3

this is obviously a DJ mix, so it's kinda hard to seperate the songs. But, the first song in the mix is Justin Timberlake's - "my love", but just the instrumental, then it goes into a Pitbull song, the title of which i'm not sure. Everything else is Bay Area rap, which we (I was actually born and raised in san jose) call Hyphy.... There are several mixed CD's out right now. Oh, I also heard Notorious B.I.G for a couple seconds.
