Discovered a powerful heuristic for track selection which helps you to find track combinations that “work” very well together. “Mixing in key” is a fairly popular method for track selection. Basically you want to find tracks that are “compatible” in a musical way. I’ve found that following the circle of fifths either clockwise or counterclockwise, always skipping 3, leads to some really astonishing results.
Here’s an experiment, using counter-clockwise circle of fifths traversal on the song keys. Note that some tracks end in a different key than they start, so you always have to take that into account.

Can you explain that a little more? I have trouble understanding what you’ve done here…

Smooth transitions and a wide variety of sounds, a good listen.
Experiment = Success!

Check out “http://www.harmonic-mixing.com/pix/easymix.jpg” — If you were on, say, “6A”, you might go counter-clockwise by 3, moving to “2A”.

Thanks for the info. I reread this with a clear mind and it makes sense. I actually do stuff like this all the time, but more on gut feeling than so mathematical. I like it this way better. Gives it a little theory…
