"He wrote the hell out of it"

Just laying in bed here tonight, falling asleep, when the thought/voice comes into my head: "That was the best song ever. He wrote the hell out of it."

I have no idea what that means. I don't know why I get these things, or how the brain works, but any time I'm not too tired and I can relax deeply without falling asleep, I get to "hear" things like this.

I put the word "hear" in quotes there, because while it is a voice that I hear -- and in this case I could tell it was a man's voice -- I don't hear it in my ears. I just hear it somewhere inside my brain, if that makes any sense.

For the record, this happened at around midnight last night, after I had been laying in bed around 20 minutes.
