In reply to iantoday:
I am pretty sure forums are meant for discussion; discussions involve opinion and he is giving his. I don't think he was dismissing the achievement (in fact he did the absolute opposite) as much as commenting on the choice of music.
I enjoy a well edited climbing video as much as the next guy so I don't see any reason not to comment on the quality of the edit and choice of music. Let's be honest, if it was horrible gangster rap then you might agree with him!
