In comparison to other dance charts, American commercial radio's definition of dance music is arguably more marginal, which is reflected in the chart's content. After the alterations made in 2011, the chart somewhat moved away from its initial purpose of charting conventional dance songs, instead including more remixed pop and urban songs in place of traditional forms of dance music and/or music by dance artists. By 2012, however, the influx of EDM songs in mix shows and the addition of two additional dance outlets amongst those monitored once again increased the dance content found on the chart, thereby decreasing to some extent the number of remixed pop and R&B tracks included.
