Okay now that the tread gets some unforeseen attention, another of my all-time favorites, and No. 2 on my playlist : After Dark, the seventh Bleach Opening.

This song and the animation conveyed the feelings from the Hueco Mundo arc greatly. He can't do it, he is against impossible odds, but he still goes on with a smile, because giving up is not an option.
Always puts me in a good mood and gives me hope. The best is Ichigos smile at the ending. Suzume!
