Houston broke so many records during her lifetime. Many rate her the best female singer of all time. Technically, she is also the best selling, in spite of the crazy, unproven, unsupported sales figures a certain jealous female singer is claiming in trying to steal the title. Posthumous sales will also help to solidify the title.
