I was under the impression that you had to write your own song for the backing track, am I wrong? Also you can enter until the 28th
I'm not 100% sure about writing your own song (it might have been suggested someplace, I didn't read everything too carefully).
Regarding the entry dates, I read through the rules a few times and I was under the impression that you could submit a video as late as August 11th, but that a winner wouldn't be chosen until August 28th.
It seems as though part of it is a popularity contest, and that Joe chooses the finalists out of a pool of the people who have the most fans. I could have that wrong, but that's the impression that I got (like I said though, I read through it, but probably not carefully to get all the details right).
I just figured, I'll record something, submit it, and see what happens. If I win, cool, if I don't, that's cool too. If this contest existed about 20 years ago, I would probably be more excited, lol
