The song nearly reached the top of the charts, peaking at number two (behind Starship's "We Built This City") on the US "Billboard" Hot 100 chart, although it did reach the top of the "Billboard" Top Rock Tracks chart.  This song, along with Jan Hammer's "Miami Vice Theme", helped the "Miami Vice" soundtrack album reach the top spot of the "Billboard" 200 chart for 11 weeks in 1985, making it the best-selling album of the year and the most successful TV soundtrack of all time.

The album charted at number 116 in the U.S. and number 92 in the UK.

The album achieved Gold status by the RIAA in the US.  It is generally regarded as the culmination of the smoother, more adult-oriented sound of Frey's solo work.
