These two singles became her biggest sellers in the United States, each earning an RIAA Gold certification. (Note: in 1981 and 1982, when these singles were certified, the RIAA standard for Gold singles was "more than 1 million copies sold"; in 1989, RIAA lowered the standard to 500,000 for Gold single certifications.) The songs were also sizable hits in Canada, Australia, Germany, the Netherlands, and other countries. For example, "Angel of the Morning" peaked at No. 1 in Canada and No. 43 in the UK Singles Chart in 1981. While "The Sweetest Thing (I've Ever Known)" failed to receive a U.S. certification, the song's popularity propelled album sales from Gold to Platinum, and the recording remained in the Top 40 (of the Hot 100) for 18 weeks. "Shot Full Of Love" was released as a single in the UK, but failed to chart.
