Yes it is about listening to Undo by Bjork!
In his diary "Dawn" there's a chapter where Phil is having a tough time being away from his friends and family and he breaks down while cooking dinner, but Bjorks magic makes its way to his headphones helping him have various epiphanies. In the song he is reciting the chorus of Undo as a prayer and reminder. The little floating head at the door is Bjork coming into the room via headphones and Phil's imagination.
