Flashback is the fifth studio album by Puerto Rican reggaetón recording artist Ivy Queen, released on October 4, 2005 through Univision and on September 15, 2007 as Greatest Hits in Germany and Spain. It is often considered as a studio-compilation release due to the amount of the album being previously released material. Queen began working on Flashback after the moderate success of Real in early 2005. Featuring content dating back to 1995, when she was still a part of the all-male group The Noise, the album includes four new pieces of work all produced by Rafi Mercenario, the genre's most requested record producer at the time.
The four tracks were written and recorded after the end of Queen's nine-year marriage to Omar Navarro, months before the album's release. Lyrically, the remaining sixteen tracks tell stories of female empowerment, love and heartbreak and sociopolitical criticism. Following an international tour of South America which began in 2004 and presentations in the United States, Ivy Queen partnered with the co-founder of Perfect Image Records, José Guadalupe, to form her own record label Filtro Musik and signed a distribution deal with Univision Music Group in 2005.
