"Goats Head Soup didn't - and still doesn't - sound like what one would have expected from the Stones after Exile ... But after ten years of recording, touring and the accompanying excess, the Stones sound burnt out, regretful, melancholic, even at times vulnerable - in other words like human beings, not invincible rock gods. How many times has that happened with them? Not many, which lends the best parts of Goats Head Soup a mesmerizing mood all its own. Adding to the album's legacy, let's not forget that "Waiting on a Friend" was born during the making of this record".
