What somebody else mentioned is right, that most of the votes are going to go to the most popular songs, not necessarily because the people who voted them are fanboys or fangirls, but because they are the songs everybody wants, and a 'Best of' album contains what the name suggests - the best of X Japan's music catalogue.. unfortunately, not the best of unreleased demos, outtakes or the best of the new songs Yoshiki has wrote so far.
But just think that one more vote for 'Others' is one more song opening that could be something new or that we haven't heard before, and hopefully that won't be a karaoke track, or an instrumental, or a remix
