Halloween has a huge fan base, and even though I'm not as crazy about it as some others, I always look forward to the spooky season.
But my love as a fan is first and foremost for music, so I've always wanted to combine these two things.
The little ghost didn't want to tell me exactly what he was listening to, but you don't have to reveal everything... Maybe his new owner is better informed or even has some influence on the songs that are played.
