is a list of the top 10 songs published in Billboard magazine primary or secondary?

Answer 1

A list of the top 10 songs published in Billboard magazine is considered a secondary source. This is because it summarizes and analyzes data from various primary sources, such as music sales, radio play, and streaming statistics, to compile the rankings. The Billboard charts themselves are based on original data, but the published list is an interpretation of that data rather than the raw data itself.
