Destiny was pretty good. That was an interesting trivia on the wiki about the line distribution between the idols. Never would have thought of it.
But, what struck me the most was that feeling I got while listening to Destiny. I know this sounds really stupid. It's hard to describe, but it's like when you realize "Wow, I've been a fan of this franchise for this long?". And, you start to recollect all your memories and experiences with im@s by the end of the song. It's like a feeling of nostalgia, and it reminds you why you still love the franchise. (I don't know.)
