Grammy-winning US songwriter Billy Steinberg, a key figure behind a string of chart-topping hits including Madonna's Like a Virgin, has died at the age of 75. Steinberg's family described him as a "visionary lyricist, devoted husband, loving father, and one of the most influential songwriters of his era". With Tom Kelly, he also wrote classic 1980s and 90s songs like Cyndi Lauper's True Colors, Whitney Houston's So Emotional, The Bangles' Eternal Flame, Lauper and Roy Orbison's I Drove All Night, and the Pretenders' I'll Stand By You.
