hehe I am one of those pedantic people where everything has to be "just right".. I spend hours and days on working out individual lines to my lyrics.. re-writing them and so on until everything is just right.. then I start to work on the arrangement and that, for me, can take weeks to get it just right.. It's just my own personal process for song-writing.. I don't write to a schedule. I wrote and recorded an entire album, in the space of a few weeks about 10 years ago.. and I wrote a full, complete song by myself in a couple of days, years ago as well.. but neither of them are anywhere near the standard I expect from myself these days.
But in the end it's more about my personal creation/song-writing process than anything else. :)
