The trouble with buying CDs is that you don't really know if you're going to like more than one track until you've bought it!
iTunes sell tracks separately and I believe this has impacted on whole CD sales.
I think $15[Aus] is a good price for the actual CD, and about $6 for the MP3 download.
Talking about "authentic crackles", didn't Steeleye Span have a track with a built in jump?
