Under construction: An experiment with music

This is an experiment.  To get the full effect you'll need headphones.

For decades I've loved a certain kind of music--not "popular songs" but intricate compositions that I feel often convey deep meanings--or perhaps just put many listeners in a state of mind that leads to contemplating deeper things.  Some of the songs below have (literally) tens of thousands of comments on YouTube saying essentially the same thing, so it's not just me. 

So the experiment is, pour yourself a drink, don your headphones and click the ones that are blue, in order.  If any of these made your mind wander, feel free to leave a comment.
