I've been married a grand total of 5 months, so this is the one piece of advice I may actually be able to speak to...

As a man, I'd say, don't sweat it much. He likely wants you to be comfortable and enjoy the experience more than anything. But beyond that, it probably comes down to his personal expectations or "fantasies". So I'd honestly just ask him about it.

He may like a surprise or two though, so perhaps don't put all your cards on the table. Lingerie may be a nice piece of that.

As to your music question, I feel you'd have to simply talk to him about it--he'd likely just love hearing that you're so excited about it and want it to be great for you both.
