 In the issue of "Billboard" dated March 30, Canadian singer Celine Dion, one of the most successful pop/AC acts of all time, reached number one with "A New Day Has Come", the lead single from her first album after a hiatus from the music business during which she gave birth to her first child.The song would go on to hold the top spot for 21 consecutive weeks, breaking the record for the highest total number of weeks atop the AC chart previously shared by "You'll Be in My Heart" by Phil Collins (1999) and Dion's own "Because You Loved Me" (1996), both of which spent 19 weeks at number one.Such lengthy spells in the top spot would become a feature of the AC chart in the 21st century
