I had so much fun with my first music themed puzzle cache, GC7F7JK, that I decided to use the same two songs to do another one! It is not necessary to solve that puzzle first in order to do this puzzle.
If you'd like to hear these songs, I recorded them for the first puzzle and it's posted on YouTube here North and West
I actually made this a two stage puzzle. So, once you solve the puzzle you'll need to get some information off of the electrical boxes to get to the final stage. No container at Waypoint 1.
This is a hard puzzle! However, there is nothing arbitrary about the correct answers. I structured the options kind of like a standardized test - there are some answers that may seem right, but you are looking for the BEST answer. If you have questions, feel free to message me.
Congratulations to the5millers, PoshCacher and MagicCacher who I'm sure learned way more about music theory then they'd like to think about!
Waypoint 1 is at N 39 AB.CDE W 104 FG.HIJ

You can validate your puzzle solution with certitude.
Once you're at Waypoint 1 look for the four digit number on the electrical box.
If the second number is 5, add .016 to the North coord minutes
If the second number is 6, subtract .016 from the North minutes
If the fourth number is 0, subtract .098 from the West minutes
If the fourth number is 1, add .098 to the West minutes
Now you're on your way to the final! Have fun!
