William Shakespeare, in the opening of "Twelfth the Night," wrote, "If music be the food of love, play on." And so when music and love collide, a strong bond is formed.

Several pairs in the music industry found their harmony with each other having their hearts beat as one. Take a look at these six thriving power couples who create beautiful music together until now.

The ultimate superpower couple, Shawn Carter, best known as Jay-Z and Beyoncé Knowles, has been married since 2008 and has three children, Blue Ivy and twin brothers, Rumi and Sir. Their 12-year union gave the couple a combined net worth of $1.4 billion, according to Forbes. Hov and Bey's best collaborative works include "Crazy in Love," "Drunk in Love," "Déja Vu," and "03 Bonnie and Clyde." The most powerful couple had its share of high profile controversies when Jay-Z admitted to infidelity. Queen Bey had put a shade on his cheating on some of the lyrics from her album "Lemonade."

Their relationship could have started as teenage love when they met up for the first time. Kaseem Dean, his real name, was 16, and Alicia Augello-Cook, then 14 were introduced through a common friend. Keys, in her new autobiographical book "More Myself," admitted she never liked the young man at that time. Maturity caught up with them, and the two found themselves working together for a music project. The more time they spent with each other led them to the altar in 2010 and a baby boy in the same year. Keys gave birth to another son in 2014. The low-profile couple came up together with songs "Waiting for Your Love" and "International Party."

Country music royalty McGraw and Hill started their relationship on the right foot - singing. Hill was the opening act in McGraw's 1996 concert tour, and the two went on a whirlwind romance that led them to a wedding in the same year. Their almost 24 years of marriage gave them three daughters. In 2017, the power couple celebrated their 20 years of togetherness with a first joint album, "The Rest Of Our Lives."
