Diane Warren has had one of the longest — and most prolific — careers in pop songwriting of anyone in the music industry today. You’ve heard her music, even if you don’t know her name: she is behind hits spanning over three decades, from Aerosmith’s “I Don’t Want to Miss a Thing” to Celine Dion’s “Because You Loved Me” and the Michelle Obama collaboration “This Is For My Girls.” Over the years, she’s racked up a series of accolades, too, including 15 Grammy nominations, nine number-ones on the Billboard Hot 100 and nine — count ’em!
