I listen to music sometimes when I write, but any suggestion like the following:

Basically, I just open up a text editor on my computer or get a pen and pad and just close my eyes and let the music play. I write whatever comes to mind.

has never worked for me, ever. I feel like George McFly after Marty tells him to say to Lorraine "whatever comes to mind". He stands there a moment and then says, "...nothing's coming to mind."

Music works for me if I already know what I'm going to do. Otherwise it's simply a distraction and doesn't help me invent an idea that wasn't there previously -- like most things.
