I could only think of one, and it might be a little bit of a cheat: "The Samurai in Autumn" by the Pet Shop Boys. I do, indeed, know all of the lyrics, which are thus:
It's not as easy as it was
Or as difficult as it could be
For the Samurai in autumn
And no more than that in this largely instrumental track. Certainly not difficult to remember, and I have always imagined that the lines are about the boys themselves in their late career period, when only the diehards care anymore (although, knowing Neil Tennant, it probably has to do with an historical figure).
I've always found this to be the highlight of their Release album (2002), which turned off the hardcore synthpop crowd with its "rock" aspirations. This peppy yet moody dance number, plopped midway through amongst dense, boring guitar slogs like "Birthday Boy" and "Love Is a Catastrophe," feels like PSB doing what they ought to be doing; it even evokes the brilliant experimental vibe of Relentless.
