First choose any decade from the 1950’s thru the 2010’s by entering the first year of it (i.e. ‘1990’). Then, name the artists which had only song in the Top 40 charts which peaked during that decade. Sorted by most recent to oldest peak position on the top 40. Song and year of peak position shown. First two words accepted for longer artist names. Keep in mind some of these are multiple artists, the individual artists may have had a top 40 hit, but the combo of artists only had one.
