"Aquí Estoy Yo" was released on October 13, 2008, as the second single from Palabras del Silencio, the seventh studio album recorded by Puerto Rican singer-songwriter Luis Fonsi.

"[2] While on a boat fishing with Bisbal, Syntek and Schajris, Fonsi asked them to record the track, since it was "an amazing song and the only thing I do is look at three musketeers sing to me".

[10] "Aquí Estoy Yo" became the first number-one single for Aleks Syntek whose previous highest rank on this chart was achieved in 2004 with "Duele el Amor", a duet with Spanish singer Ana Torroja that peaked at number two.

[12] On the Billboard Latin Pop Airplay chart, this song replaced Fonsi's "No Me Doy por Vencido", which led the list for a chart-record 28 weeks.

Juanes' "Gotas de Agua Dulce" followed by "Me Enamora" on the February 23, 2008, and Ricky Martin's "Vuelve" gave way to "Perdido Sin Ti" on September 12, 1998.
