"SVAKA SLIČNOST SA GRUPOM „POP MAŠINA“ JE SLUČAJNA I NENAMERNA!" = "Every similarity with the group „Pop Mašina“ is accidental and unintended!" printed on back cover is of course a joke by the band - factually, „Rok mašina“ is follow-up to „Pop mašina“, it is the same group but renamed and with small personal changes.
