Great songs and artists who virtually own them?


In professional sports, when a player does such honor to his number that nobody else can live up to the legacy, that number is frequently retired. My question is simple: Are their artists that performed a great song so right, that nobody else can touch it and do justice to it? e.g., Etta James - "At last"; Billy Holiday (Sorry Frank) - "One more for my baby".
