Thank you for your comments, John. And this one couldn't be more 
timely, as I'm beginning to format a new CD release. I have my own 
ideas on how to proceed, but I'd appreciate any input from the brain 
trust here.

What are your thoughts about a good length for tracks on a soundscape 
CD -- not bird or frog ID clips, but soundscapes purely for listening 
enjoyment. If there's a standard to go by, I don't know what it is. 
Anyone willing to offer wise counsel on this?
