At FiveTracks, check out the Top Five Songs About Food and rock out! I would have several songs to add to this list, including but not limited to:
"Cherry Pie" by Warrant
"Brown Sugar" by the Rolling Stones
"Peaches" by Presidents of the United States
"I Want Candy" by Bow Wow Wow
"Cigarettes and Chocolate Milk" by Rufus Wainwright
You could make a solid argument that any or all of the above listed songs aren't really about food, and I might not argue with you. For your enjoyment, here is, IMHO, possibly THE most artfully metaphorical song/music video of all time.
