One of the things I love about big ensemble numbers in cast albums, thought is can be true of other things too, is that different parts are noticeable on each listen.
There's a saying along the lines of when a student is ready, a teacher will appear. My interpretation of that is that when you go looking, the answers and/or the teacher will be there. After all, there are so many things to do and learn, we all tend to tune out a lot of it. But when you look around for it, there it is. Sometimes it's hiding on a corner of the internet, but it's there.
Even sometimes when listening to the big numbers with the lyrics in front of you, part of it skate past. You know the words, you've heard the words. But maybe you like humming along to that bit over there. And one day you will notice that these two lines, actually mean this and you have an oh wow moment. Sometimes over a song you listened to a gazillion times.
What's funny, is about half the time it's so obvious once you see it. And you find yourself trying to explain to someone, well yes, I know they say, "the stars are out tonight," I wasn't confused about that. I just hadn't connected to the part about the stars from earlier.
There are so many delightful things to read, watch, and listen to that repeats sometimes seem silly. But there are new delights to be found even in familiar things.
