1. "My Neck, My Back (Lick It)" by Khia
The ultimate rubberneck moment for first-time listeners: Wait, did she really? Was that? It was. It's a fine pop song with a catchy hook (the unforgettable "Lick it now, lick it good, lick that pussy like you know you should") and one of few to mention crack in a non-narcotic context. Extra points for the parentheses.
