Query: Dr. Dre before "The Chronic"

This is Dr. Dre's collection of old and new hits before the now infamous "The Chronic" album.Deep Cover a.k.a. "187 on an undercover cop" introduces the world to Snoop Dogg.Bridgette is the only leftover song from The D.O.C.'s album, and probably the most memorable one at that.Turn Off The Lights by the World Class Wreckin' Cru, old school classic!Those are the only notable songs that stick out for me at this moment, a must have for any true old school/rap/hip-hop fan.
