Manuser, I think it's really your very own personal opinion and taste.
That track has for me a real story, 160 BPM was not a choice for me, but the expression of my mood when I produced it (say, I was very angry, maybe...).
Anyway, maybe it was a mistake, or not... Or maybe a track has to be respected the exact way it was created. You just don't like it like that, your taste (again).
I was not aware of that "150 BPM version on YouTube"... Or a topic on the forum just about that.
That said, maybe you will be happy to hear that the live version (the one I play usually with my violin in all my live-acts), plays at... ... 150 BPM !!! Ta daaaaaaaaaaaa :-D
Anyway, thanks for the comments, I always appreciate !
