The current iteration of this page says the chart began on 23 May 1969, but I see on its website that it has chart info going back as far as 3 October 1956. Are these real positions assembled by a magazine or radio station, or were they compiled decades later? If it's the former, what name(s) did the chart go by from 1956 through 1969? I don't speak Dutch, so the website isn't much help to me in researching its history. Tkbrett (✉) 22:59, 21 June 2022 (UTC)[reply]

UPDATE: Relevant discussion takes place at Wikipedia talk:Record charts § Archive 18 § Dutch Single Top 100.

From 3 October 1956 to mid-1957, the chart was Elsevier, and after mid-1957 it was Muziek Parade [nl]. Presumably this lasted until 23 May 1969, when the Dutch Single Top 100 came into existence, but I am not certain of that. Tkbrett (✉) 11:29, 2 June 2023 (UTC)[reply]

Now that I look through it, I am uncertain. The Lovin' Spoonful's single "Daydream" reached number 15 on Muziek Parade in June 1966 and number 12 on Muziek Express in May. Both of those charts were monthly, yet the Dutch Single Top 100 chart shows a weekly chart, with "Daydream" reaching number 11 the week of May 7, 1966. I am starting to think the Dutch Single Top 100's pre-1969 charts were retrospectively compiled. Tkbrett (✉) 11:52, 2 June 2023 (UTC)[reply]
