It's the cruelest joke to play. When kurt would get so high, he would look like an idiot and try to run in place. He kept on playing some stupid song when he needed you, and he needed you. It's all he's got when you're in his head. And you're in his head, So he played it.

You were the only thing Kurt's got...and he couldn't seem to get enough. He was all over you all the time. And he didn't want to leave you. You both had to move for one embrace, so he counted you as part of him.

He kept on playing your favorite song, and turned it up whenever you were gone. Again, it's all he had when you were in his head, stuck without a purpose. And you were in his head. So he needed it.
