Snuffy you seem like you only have to hear a song once and it sticks in your head you know so many!
I am with the first word of the verse pricipal, and with songs like Row on where I can't see a logical progression in the verses I make a mental picture using these words so below the clouds is a Bear standing by a river, he sees a star which lights up the row boat.
I think it is called mind mapping, once you spot the links you can use any imagary to connect them, the more wierd the better you are more likely to remember it!
