23 For your 30s?

People say Pol Roger is 23 for your 40s. What song is for your 30s? 50s? 60s?

I think for your 30s I'm thinking 555? You go from the '20s with all it's drama, idealism, big dreams.... "I'm here, I'm now, I'm ready, holding on tight", into the reality check of turning 30, already along some kind of path but realizing it's harder than you think, and you're wondering "why does it feel like I'm moving in place?"

For your 50's... Diamond? Has some comedy and feels lighthearted. Knowing there's improvements to be made, but assured everything will come in due time as it has already proven to do so far.

80s and beyond maybe Goodbye Sky Harbor?
