Yeah, besides the odd conversation scene, I think being able to access your armour from the launch bay took away the only real reason to go to the captain's cabin at all. It would have been better if they kept your trophies/souvenirs from ME2 and continued to add to them. I mean where is the photo of your LI? Where is the crystal shard "Eve" gives you? I'm not saying it should have turned into a flee market but it would have been nice to acquire some more personal touches. They even took away the ability to review your achievements/medals for some odd reason.
And yeah, the stock music in the cabin is pretty shite.
