I like Fukai Mori (Deep Forest) the best. I don't know why, but it grabs at me. Maybe it's because the second time through the series, I realized just how much respect Sesshoumaru has for his father. Every Heart is second-best.
And no offense to you, Michael, but I thought Come was rather bland. :/ (By the way, how far has Cartoon Network gotten? I remember the beginning of the Shichinintai arc....)
