For my job, I live and breathe music discovery, playlist generation, and digital media management, so it isn't very surprising that I didn't find much in David Jennings's book that was new to me. There are some decent references here, and the chapters about music discovery (and the different ways different groups of people achieve it) are pretty good. I'd love to go on for pages about this, but that probably wouldn't go over well at RhymesWithNose.

I'd seriously consider giving this to a new hire in my group if they had no background in music discovery, and I guess that's a recommendation.
