Last night I dreamed I was the last DJ on Earth

I'm standing in an empty ballroom, all the tables still set, candles burning down to nothing. No guests, no bride and groom — just me and a stack of records I don't recognise anymore. I keep playing them anyway, because what else is there? The weird part wasn't the emptiness. It was that every song I dropped sounded exactly right, and nobody was there to hear it.
