premise: Lament is the seventh studio album by British new wave band Ultravox, released in the UK on 6 April 1984. It was the last album featuring original drummer Warren Cann until the band's reunion album "Brilliant" in 2012. The album peaked at #8 on the UK album chart and was certified Gold by the BPI in June 1984 for 100,000 copies sold. It also reached #25 in Germany and #115 in the United States.
hypothesis: Being in the top #100 album chart for the US, Lament was very popular with the American speaking audience. 
reason: Lament was not in the top #100 on the album charts for the US. I believe the AI was unable to determine that being #115 is not a sign of high popularity.
