The John O'Callaghan remix received much support from Paul Oakenfold and the rest of the trance DJs in 2012. It might have also been among the top Beatport trance tracks back then.
My favorite version is still the original mix, though. The breakdown is especially phenomenal, and you can hear Magnus' signature style throughout.
I can't really choose between the original and the Activa remix. Love both artists and both of their styles. Either way, this was my introduction to Magnus' work and damn did it make a great first impression.
