Over the course of decades, there are few songwriters who've made the kind of impact on pop music that Diane Warren has, and for her exclusive playlist for International Women's Day, she's turning the focus on some of her own estimable contributions. Namely, "I Was Here", immortalised by none other than Beyoncé in 2011. “['I Was Here' is one of my favourite songs I have ever written,” Warren tells Apple Music. “It is about wanting to truly leave your mark in this life. It's about wanting to make a difference, in the world, in someone's life. It's what I hope to do with the songs I write, including this one. Having Beyoncé bring it to life was a dream come true, because she has lived every word of it and makes you believe that with every single note of it she sings. I was here. I lived. I loved.”
