In the bath was one of Klaus' favorite places to listen to music, to just close his eyes and lose himself in the heat and the sound and know that for that little bit of time there was nothing else in the world but this. Ben left him alone when he needed time like that, so it was one of the few times he could feel like he was almost normal, you know in a stoned out of his mind kind of way.
This wasn't bad though, this listening to the quiet hum of music from headphones that weren't actually on your head and the nearness of someone else.
When Regulus took off the headphones Klaus was ready to take them back to talk maybe or something like that but instead he did something, said a spell maybe and suddenly there was music without the need for speakers and Klaus was charmed.
"Okay now that is useful," He laughed, "This music is a little older," He admitted, "But it's classic and it's hard to go wrong with the classics. It's always the kind of stuff we listened to growing up." When they were allowed their free time of course. "New stuff can be good too, but I always go back to the oldies."
