Too Subtle For Me

Over the course of the weekend I've listened to the new Maximo Park album ("Our Earthly Pleasures") around four times, and I'm really liking what I hear - the winning formula from the first album remains, but the lyrics have become even smarter.  My favourite couplet so far is "Five times five equals twenty five - don't you know your times tables by now?" on A Fortnight's Time.  Fun though it is, I haven't got the foggiest what he's on about, so I did a quick Google search in the hope of shedding some light.  The only result I turned up was this album review which cites the same lyric as an example of "just the right amount of humour and subtlety" - hmm, it's perhaps a little too subtle for me, but I'll happily sing along!
