Mhm. I voted for Sunday. My best guess is that HTT as a name is more recognisable than the other song names, so maybe it was picked like that? It's a pretty hard song to access too. The only video I know on youtube that has it is Vimi's 5th anniversary AMV. Either way, I've still got my money on Diary winning overall.
