Stairway to Heaven

Stairway to Heaven never had a single release — and it's still the most requested rock song in radio history.

Led Zeppelin recorded it in a damp country house with a mobile studio parked in the driveway, and the words came to Robert Plant almost all at once, by the fire. Decades later, courts, radio countdowns, and one very famous guitar-shop sign are still arguing about what it means and why it won't fade.

What's the line from this song you'd never get tired of hearing?
