Three singles were released from the album: "Welcome, Machine Gun", "So Many People" and "It's Me, Cathy (Follow My Heart)".

[1][2][3] The band's 1987 single "Military Drums" was also included as a track on the Japanese and US editions of Sound of My Heart.

Although pop radio at large may miss the boat on this one, tracks like "Cathy" and "Carousel" may appeal to the more adventurous programmers".

[6] Barry Walters of The San Francisco Examiner noted Kemmler's "soaring, stylish tenor" and Cretu's "lavish, invigorating production" on the album.
