What a great topic.
I definitely have song writing spurts.
I hear a phrase I store it away in my pea brain till something else comes along that I can add too.

I find it best not to force my self to write and from time to time have to give song writing a break.
I find it best to be relaxed when writing.( a few beers help)
Im trying to be humble when I put this down but I have written over 1000 songs most of which are pretty crappy and most of which you guys have had to suffer through here.
My best songs I write in my sleep but never wake up in time to record them.
You should here some of the great Beatles song I have written while asleep.
Wish I could recall them myself smile
