By Piya Sinha-Roy LOS ANGELES (Reuters) – Heartbreak paid off handsomely for British soul singer Sam Smith, a newcomer who won four Grammy awards on Sunday including record and song of the year for his anthem “Stay With Me.” The 22-year-old was also anointed best new artist and his debut album “In The Lonely Hour” won best pop vocal album. “Thank you so much for breaking my heart because you got me four Grammys.” The music industry’s biggest night took on a somber note with a powerful message against domestic abuse delivered by President Barack Obama by video, by a survivor’s testimony and by a Katy Perry performance. While Smith was favored to win big, Beck pulled off the surprise of the night in album of the year, beating out Smith, Pharrell Williams, Beyonce and Ed Sheeran.
