Well, it looks good to start. But remember, there were multiple charts during the 1948-1958 timeframe. All we have right now as a reliable source is the series of Joel Whitburn books, including "Top 40 Country Singles" and "Top Country Songs," so the best we can probably do is state how long each song spent at No. 1 on a given chart, and place said information along with the requisite notes we've had before (whether it was their first and/or only No. 1 hit, if the song dropped from No. 1 and later reclaimed the top spot, and if it wound up being the No. 1 song of the year). The song's No. 1 date would be the earliest it topped any of the charts, just as it is listed in Whitburn's books.
