or did you decide to do the explosion after already having written the 1st few choruses, choosing to take what was already there and just run away with it?
wasn't a choice. it was quite involuntary. had to work some details to get the right combination of lyrics and detials to guide it safely to an end, but that chord sequence exerted itself forcefully onto the scene before i had any say in the matter. to be fair, that's how songwriting goes. if i'm trying to 'decide' how it goes then i probably won't get anywhere
