You can argue that "Hotel California" is overexposed.  But love it or hate it, it has all the essentials of a great rock song: interesting and quotable lyrics, guitar work even the snobs can appreciate, radio-friendly hooks, and the distinction of having inspired an urban legend.  (No, there is nothing occult-related in the song.  Its true subject, the decadence of Southern California in the late 1970s, is frightening enough as it is.)  It's one of the great songs of its era.
