My experience with this idea is that it doesn't work unless you have good people who are actually -capable- of using their creative brains and doing things with their own initiative. I offered this to my software team, but am yet to see them actually doing anything with their time. I have to really push them to make them use it. I guess it's my fault for hiring them, but still, it bugs me.

The problem with these blind tests is that accurately picking the difference between songs is a very difficult task, but not necessarily because people can't hear the difference. Unless people have practice in this type of test, they start thinking too much and the results become biased for all types of unimportant reasons. That's why you have such an outlier in the first sample. For those of you who don't know much about wine - think of those times when you've been wine tasting. You know that there is difference between the wines, but can you actually discern which is the 'best' when you're at the cellar door sipping on 10 different choices? How often have you bought something, only to find when you get home that it wasn't what you expected? Whilst the best wine will almost certainly be much more enjoyable when it comes time to drink it, actually picking the best wine is best left to the pros.
