This is the 2 track promo (test pressing-blue acetate) CD single for the song "Only Girl (In the World)" from Rihanna, released strictly to radio in 2010. Tracks include: 1. Main (3:57) 2. Instrumental (3:57). CD comes in a generic black cardboard sleeve with window. Everything's in very good condition, never been played although disc has one mark across disc from mishandling, not really on play area, price reflects this
