Song Help from Training Day

Rating: Null/10 (30 May 2005)

I need help with this question. I've been trying to find this song for a week. I believe its one of the first songs played in Training Day. I wish I could remember the lyrics but I just can't seem to. The beginning of the song is really punctual and it seems like its one of Dr. Dre's songs. Does anyone know the song from Training Day when Denzel and Hawke(Alonzo and Hoyt) get out of Denzel's (Alonzo's) car, and/or when he turns on the hydraulics in the car and they start moving.I think its from the beginning. I also think its Dr. Dre but I'm not sure, does anyone know? Please Help me. Thank you a lot for your help.
