With the initiation of the Hot 100 in 1958, A- and-B-sides of singles charted separately, as they had on the former Top 100. And indeed, prior to this week, “Come Together” had peaked at #2 and “Something” peaked at #3 as separate entries on the chart.

But starting this week, this rule was altered; if both sides received significant airplay, they were listed together.
