Beck - "Mexico"
I was going to claim that this one gets most of its charm from being mentioned by Greil Marcus in the discography of Invisible Republic, where I learned that Beck got the music from a folk song called "The Hills of Mexico." Then I was going to make fun of all the slacker elements of the song, complete with a snide aside at "lo-fi", but you know what? This song is absolutely charming; a goofball story with an ending to the story that is absolutely brilliant. Though it doesn't make me want to become a Scientologist, it does make me want to go for a Big Mac and normally I'm a two cheeseburgers guy.
