I just love the first video. It is really inspiring, and I re-watch it often.

I also like this version: http://www.youtube.com/watch?v=djnGjm-BfdI . Sunshine's OST, Adagio In D Minor ( http://www.youtube.com/watch?v=NQXVzg2PiZw ), goes really well with the message. Of course, some might say that this song could make any video "epic"... They used a remixed version of it in Kick-Ass: http://www.youtube.com/watch?v=-dQMunLEXHA (warning: SPOILER!).
