I sent out the Mass PM last time when it came to song submission, but Mass PM's are currently disabled, so I don't know how to spread the news of this contest (profile comments spree isn't going to work, this club has too many members for that to work). But, I'll see what I can do.
I want to vote for Higurashi instantly, but I'll watch the videos first. Couldn't do it last night, my internet is too slow at home so I had to go to my uni campus.
10 minutes later...
Still voting Higurashi. Watching it brought back some fun memories. Eden of the East and Mouryou no Hako OP's were good songs though. Really liked the visuals on the first song. Going to edit Ignite's first post, updating the links for the Mouryou no Hako and Darker than Black OP's.
