After a number of back and forths, and trying to determine which playlist best fit what I was looking for... I still had no winners, as there were a great deal of awesome playlists which were submitted for the Summer Solstice. So I went with sheer favoritism based on my personal tastes. And in a very very close decision, simply had to go with Corpsegoddess' playlist because it was like she ripped the majority of it from my head.
Her playlist is provided below, and we'll wait for her to choose what our next theme shall be.
I would rather not dwell on runners up, but I will state that there was not a single submission which was dismissed, all were listened to, and I have some new listening habits thanks to them.
