Whitney Houston was barely out of her teens at the time of her 1985 debut, which makes the sensuality of slow jams “You Give Good Love” and “Saving All My Love For You” even more extraordinary. “How Will I Know” is so cotton-fresh that other ‘80s pop hits sound dull by comparison. On the ballad “Saving All My Love For You,” her voice is a thread that pulls us through every silky note and soaring climax, while “Greatest Love of All,” a pinnacle of soft R&B and self-love, flies to a peak that other singers are still trying to climb.
