 Carey then opted to record a new album , that would be released during the summer of 2009 . During the later stages of the project , Carey released the title , Memoirs of an Imperfect Angel , that would serve as the singer 's twelfth studio album . She explained how plans for a ballad to be released were put on hold , because a new song she had written " needed to be heard " . On June 9 , 2009 , she wrote on her official Twitter account : " Seriously , this is one of my favorite songs ever . I love the whole album . I 'm completely immersed in it . I can 't wait for you to hear it " , and announced its title as " Obsessed " . Later that week , The @-@ Dream , who co @-@ wrote the song with Carey , claimed that the song was definitely aimed at someone in particular , and that it would upset them greatly . The song was transmitted digitally to radio stations on June 16 , 2009 for immediate airplay and made its debut on Chicago radio station B96 at 2 : 00 pm . An official remix of the song , featuring rapper Gucci Mane , premiered on the same day .
