I actually made one of these last winter just for the hell of it. I was going to show the community but never really got around to it. It's a field of 64 with 4 play in games to get up to 68...With there being 72 STP Songs all I had to do was eliminate the worst 4.
If you need a hand with anything I'd gladly help but I don't want to take away from your enjoyment of making one or anything like that.
