i'm not a 2pac fan at all and i would agree that it is not one of dre's more memorable productions, but this song is the jam. and the video! a mad max themed video for a song about california? it's so nonsensical that it's brilliant.

check out the original sample sources for 'california love', they actually stand up quite well on their own:
joe cocker 'woman to woman' (joe cocker! what!)
ronnie hudson 'west coast poplock' (essential block party material)
