Thanks so much, Samuel! I'm so glad my comment made you smile! Yippee!
I've found the same to be true - when I was younger, I loved many songs but never really paid close attention to their meanings and now, they make sense and resonate deeply.
What I love about that (aside from simply loving that!), is that the subconscious is always paying attention to every single thing we think, do, say, experience, hear etc. So those songs that had deeper meanings and value I didn't recognise at the time were still having an impact on my psyche, and that "guiding light" was still embedded in there somewhere.
Pretty cool, right??
