You might find you get what you need

With each play, I tend to become fixated on one particular track and live with it for months, during the writing-my drug of choice, just to get my brain sorted. Then I'd turn off the music and start work. I wrote most of "The Coast of Utopia" between listening to "Comfortably Numb" on repeat. With another play, Arcadia, the drug was the Rolling Stones' "You Can't Always Get What You Want,"and since that play ends with a couple waltzing to music from an offstage party, I wrote the song into the ending and stayed high on that idea till I'd finished. It was inspiring. When, in rehearsals, it was pointed out to me that "You Can't Always Get What You Want" isn't a waltz and that, therefore, my couple would have to waltz to something else, I was astonished, uncomprehending, and resentful.
