Eyes of Innocence was the first mainstream release by the Miami Sound Machine. It became the band's breakthrough album due to the success of the lead single, the dance hit "Dr. Beat", a top 20 hit in Australia, the United Kingdom and other places in Europe. "Dr. Beat" was the most successful cut from the album; the song utilizes synthesizers and dance rhythms of the time, but distinguished itself from other pop music of the era through the inclusion of Latin sounds. The second single, "Prisoner of Love", was released exclusively to the European market, which was responding much better to the album than the American market had. However, the song, which had a similar sound to the previous single, wasn't a hit and was a commercial failure, only reaching number #98 in the UK Singles Chart. Due to the failure of "Prisoner of Love", another single was released to the American market, "I Need a Man", but it too bombed, failing to even enter the dance charts. With the failure of the last two singles, no more singles were released to promote the album except in the Philippines, where "I Need Your Love" was issued as a promo single only; again, it failed to impact any chart. Many of the songs from the album were originally written in Spanish and translated into English, including "Orange Express", which was the main song of the band's previous album A Toda Máquina, and "I Need Your Love", a translation of the song "Regresa a Mí". As of 2008, Eyes of Innocence has sold more than one million copies worldwide.
