Well, a song a day over three years and you'd top 1,000. I suspect there are a fair numnber of people who've written a thousand or so songs. But the thing isn't just numbers, it's quality, and there's not many could top Woody on that.

One pretty prolific lad is Leon Rosselson, both numbers of songs and quality.

But for real productivity, see this correction from the Guardian today: "In our obituary of the country songwriter Harlan Howard, page 22, March 6, we said he had 400 songs in his catalogue. The total is much closer to 4,000."

(Myself, I think I've got something over 200 - just scratching around.)
