There are a number of reasons why there can be debate about
which record should be considered to have been "Number One"
in a particular country on a certain date. These are discussed further down
this page. However there is clearly a sizable group that don't want
to know about these details and just want to know what record was top of the
charts on a given date (such as their birthday). This table shows which records
were number one for various countries over the month of May 1957.
As was mentioned above, there are all sorts of reasons why
the entries here rather over simplify the real situation. We have made a large
number of sweeping assumptions in order to present a simple picture to the vast
number of users that just want a song title. This means that there are a number
of entries in these tables that should be handled with caution. In addition where
these entries differ from the original sources (listed later) it should be assumed
that the sources are correct, where these entries conflict with the main data
assume that the other data is correct, if you find either of these cases please
tell us and we'll correct the data here.
If, like us, you are the type of person that wants to know if a song was top of the
Jukebox or Jockeys chart, or where a double-A side was released, or when chart
entries did not specify an artist, or when the charts switched from one magazine
to another we suggest that you have a look at the original sources:
