Prior to record charts launching in 1940, the music charts of the United States were based primarily on sales of sheet music. This book contains a comprehensive list of every song to appear on these charts, along with its composer, entry date, peak position, weeks at number 1 and total number of weeks spent on the chart. Also included is a complete chronological list of all the number 1 songs, and a section highlighting exceptional chart achievements. This book will complete your US chart collection with the often-overlooked charts from a time when sheet music was king.
