I'm not very good with this whole "deeper meaning" thing, but what I do know is that Journey is one of the best games I've ever played. It may be, hands down, the most beautiful game I've played. I've never been so touched by something before.
I loved the game, personally. And yes, the discs are a pain to get out. It's symbolic, really. You fighting with the case to remove the discs represents Shepard fighting the Reapers.
