Paul McCartney is 83 and still writing songs. It’s a compulsion and a craving. “It’s a magical world, music,” McCartney told The Times.
“Scientifically, even, it is just a bunch of frequencies. So how can these frequencies affect your heart?”
“I get it, if it’s got a lyric, sometimes you go, oh yeah. But if it’s just a melody — how can that make you cry? That’s magic. I love it.”
