I apologize if this is a silly question or if I'm misunderstanding, but, have you not really listened to music before? Or just not with headphones?
I've got plenty of suggestions ranging a broad variety of genres and styles but the suggestions in that situations might be a little different than if I was suggesting headphone testing music
If you decide to take the easy way out, at least do it some interesting way, like 5 fishing magnets and ropes... Run out to the space x rocket as it's about to take off.... Ohhhh add some snow skiis and skii into to space!!!
