help me to find song name

For those of you who have seen Training Day with Denzel Washington.

There is a song that is played in the background as Denzel and his training partner walk up the steps to a house. There are people outside dancing to it. Heavy bass in the song.

Its a crap song anyway. You really need some proper music. But anyway the all knowing 'me' shall help......whoever you are.

Live - Deep Enough (Hip Hop Version)
