Three different versions of Cyber by sakuraburst - Original, Remix by Arthur & Medic and VIP mix by sakuraburst as well.
They sound nothing alike except for a key vocal track and some synth details, yet you can hear that they're all versions of the same thing.
What.
(As a fun note, Arthur & Medic tagged his remix of Cyber as "the difference between good music and great music is an inhuman amount of coffee")
