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.

Queen returned to the music industry with her highly anticipated third studio album, Diva, which was critically acclaimed and later recognized as a factor in reggaeton's mainstream exposure in 2004 along with Daddy Yankee's Barrio Fino and Tego Calderon's El Enemy de los Guasíbiri.

The tour touched upon various South American countries, including her first in Ecuador, where she performed songs such as "Papi Te Quiero" and "Tu No Puedes" to promote both Diva and Real.

[7] In June 2005, Ivy Queen partnered with co-founder of Perfect Image Records, José Guadalupe to form Filtro Musik.

[8] This stemmed from Guadalupe parting ways with the other co-founder of Perfect Image,[8] Anthony Pérez who in turn would launch his own label The Roof Records.

[16] The "reggaetón-ed up twist" on Selena's classic,[22] features bitter-romantic lyrics, synthetic instrumentation and synthesizers, while taking reggae influences similar to the original.

[24] "La Mala" ("The Bad Girl"), originally featured on Don Omar's reggaetón compilation album Los Bandoleros (2005) as "Según Tú" ("According To You"), employs simple harmonic progressions and synthetic instrumentation.

[25][26] The album, which collectively brought together almost every top name in reggaetón at the time featured only one female artist, Ivy Queen.

Following this, Queen describes "a tumultuous relationship, where Ivy is considered "la mala," where in reality, "the male lover is responsible for its demise.

[35] "Como Mujer" ("As A Woman"), included on Queen's debut studio album En Mi Imperio (1996) is a sociopolitical themed song.

[41] "Yo Lamento" ("I Regret"), formerly on Noriega's compilation Contra La Corriente (2004), titled "Amiga No Pienses" ("Friend Do Not Think"),[42] contains modern reggaetón rhythm.

[45] "Miles De Voces" ("Thousands Of Voices"), a hip hop track from Buddha's Family (2001), contains simple harmonic progressions, synthesizers, affronted lyrics and a sociopolitical theme while alternating between major and minor key.

[47] "Aunque La Distancia" ("Although The Distance") was originally included on the compilation release Romances Del Ruido 2 (2003) by Baby Rasta & Gringo as "Llora Mi Corazón" ("My Heart Cries").

[61] In February 2005, further promoting the album, she appeared at the "Festival of Puerto Rican Stars", which was a historic achievement for reggaetón, as no other performer from the genre was invited to attend the event.

[63] In September 2005, she headlined the La Kalle 105.9 Block Party concert at Madison Square Garden, which grossed $962,390 for the week of November 19, 2005.

"[68] In conjunction with the launch on November 21, MTV Networks hosted "Caribbean Rising", "a series of concerts featuring performances from more than 80 artists across genres such as reggae, dancehall, reggaeton, hip-hop, and calypso.

[70] Two days later, she held her first concert at the Fine Arts Center in Santurce, Puerto Rico, where she recalled her "sojourn from little Añasco, to the Fine Arts Center stage", kissed her new boyfriend, who at the time was DJ Urba,[71] and announced plans to market an Ivy Queen shoe, clothing, and perfume collection.

The change in image for Queen is attributed to Universal Latino feeling that the album Real had crossover potential to U.S. mainstream audiences.

[75] The album cover also features Queen's signature long nails which she sports in a variety of colors; in this case they are light blue and white.

[89] On the Billboard Latin Tropical Airplay chart, the song reached #1 for the week of November 5, 2005 replacing "Amor De Una Noche" by N'Klabe.

[98] It debuted under the name "Yo Quiero Bailar" at #37 on the week of December 20, 2003 and peaked at #24 for the issue dated January 17, 2004 on the Billboard Tropical Songs chart.

[22] He started off the reviewing by stating that through the album, Ivy Queen can give insight into reggaeton to a person who is unknown to the genre.

[22] While noting that "In The Zone" with Wyclef Jean was missing from the album, he stated that it "has more than enough driving grooves, chunky beats, symphonic atmospheres, and infectious raps to compensate".

[107] Wayne Marshall writing for The Phoenix opinionated that the "retrospective of recent hits and career standouts, is a crucial primer on the reigning Queen of reggaeton".

[108] Ramiro Burr of the San Antonio Express-News saw the release of Flashback, along with Daddy Yankee's Barrio Fino En Directo (2005) and Don Omar's The Last Don Live (2004) as releases that combine current hits, remixes, live renditions and previously unreleased material, because the artists haven't had time to produce an all-new album due to the genre's demanding status, at the time.

[104] According to Noche Latina's Navani Otero, Queen represented the ladies on Omar's release Los Bandoleros with "Segun Tu", showcasing that "she too is a musical outlaw herself".

[110] Ramiro Burr of Billboard stated that "Quiero Bailar" shows how effortlessly and quickly she alternately sings and raps, claiming that she has a distinct vocal style that evokes Gwen Stefani.

[111] Kid Curry, PD of Rhythmic Top 40 WPOW (Power 96) cites Ivy Queen's release of "Yo Quiero Bailar" as "the last reggaetón super-hit".

[120] "Cuéntale" was also nominated for "Best Latin/Reggaetón Track" at the 22nd Annual International Dance Music Awards, which was ultimately won Shakira and Wyclef Jean with their #1 single "Hips Don't Lie".

[135] Pop/Rock group "SPS: Salt, Pepper and Suga" covered "Quiero Saber" on their 2005 album Armadas Con El Groove.
