You can find it in Billboard Mag. Archive in Google books. They didn't weekly publish the Danish charts, but every two weeks. I think it match the charts onhttp://eucharts.tripod.com/DE/DE9801.HTM
I'm no Danish chart expert, but I think (not sure) the charts pubished in Billboard are official????
Maybe offtopic, but the Danish charts you published here on UKMIX, they are also used to compile the Europarade.
When I tried, I found it extremely difficult and time-consuming to find anything useful in Google books. If anyone has direct links to whatever it might contain relating to the Danish charts of 1998 or 1999, they could be compared with the other available sources.
An attempt has always been made to use the most "official" available Danish charts in the Europarade - but I'm not even sure what charts those were when it was compiled by TROS, then SR-1.
In the Europarade for The Netherlands the Dutch Top-40 is used.
But... The Dutch Top-40 is not fully based on sales!
It contains a lot of airplay!
In The Netherlands The Dutch Top-100 http://dutchcharts.nl/weekchart.asp?cat=s
is only based on sales (downloads AND physical single sales!)It's better to use this chart for compiling the Europarade.
There was a discussion here not very long ago of the merits of the various Dutch charts:
including the interesting revelation that, about a year ago, for a modest outlay, a record company placed one of its acts at number one in the sales chart by downloading it 4,000 times themselves - which actually turned out to be twice as many as they would have needed to achieve the same result. When that can happen, it's doubtful that this is necessarily a better chart to use, even though the alternative includes airplay. However, although TROS used their own TROS Top 50
for a few years, and then the Nationale HitParade
very briefly, the top 40 has otherwise always been the Dutch chart used in the Europarade - and it's certainly been the longest-running and most high-profile of them all. SR1 always used it from 1987 to 1993, francisplaiy did likewise from 1993-2000, and I already have used it for 2004-present. So I will be continuing with this one for the 170-week gap (or thereabouts) still to be completed. To do otherwise would actually require quite a lot of additional time for the data collection and processing.
