Cheers-worthy lines: "There's booze in the blender / And soon it will render / That frozen concoction that helps me hang on."

The 1977 song is from Jimmy Buffett's Changes in Latitudes, Changes in Attitudes. It was inspired, appropriately, by a drink the singer discovered in Austin, Texas. The singer wrote much of the song the same evening and finished it in another warm-climate area, in Key West.

It is, to this day, Buffett's highest-charting solo single; it reached No. 8 on Billboard 100 and Easy Listening and peaked at No. 13 on Hot Country Songs. In it, he sings about nibbling on sponge cake, tourists covered in oil and shrimp boils.

The song is named after the delicious drink, with lyrics describing a vacationer's day to day activities with nothing to show for his time -- except for a tattoo. The tattoo is of a woman, and he can't remember having it inked. That, and other hilarious scenarios are sung by Buffett, and he self-medicates with margaritas, of course.

Another famous country singer--Elvis Presley--was supposed to sing the song, but he passed away the year the song was released, giving Buffett the opportunity to make "Margaritaville" a hit song.

This classic song (also the name of Buffett's restaurant chain) has stood the test of time in bars around the world, with or without salt. It also has inspired lots of products, including Margaritaville tequila, margarita mix, bottled malt beverages, branded Landshark Lager, Frozen Concoction Maker, chips & salsa, chicken wings, frozen seafood, Soles of the Tropics footwear, men's and women's apparel as well as outdoor and beach furniture.
