Embarrassing, so an error

First of gaukelt us the chart show almost every week who where the most successful song. Unfortunately, that is every time anew completely wrong! There are used every time the Top 10 of the charts, the courts 11-100 but never in the calculation. So you come to obscure Ergenisse that have nothing to do with sales figures!
The best-selling Christmas song in Germany is by far Wham with Last Christmas and not Loona or sont who. Where is the logic? Soon we calculate only the places 7-10 or how?

For CD: nice song of course there are on it, but we have yet all already. And that is just the No. 1 own distinct chart list! is not showing on the CD is incredibly embarrassing!

Conclusion: No thanks!
