What's with the version numbers?

The sources for the charts are of such varied levels of quality that there are bound to be mistakes in the way the data is assembled. There is a continual effort to fix the most obvious problems in the data, and to add in additional charts as they become available. The version number tracks these changes, so if an issue is identified it can be tied to the version of the data that it was fixed in.

The version number of this particular data set is 1.9.0031. There is a CSV File that contains all the song and album entries listed on the site.

When do you change the charts? can a song moves in the chart? what charts are closed?

As song or artist names are corrected they may affect the order of the charts. For example the Vaughn Monroe song "Riders in the Sky" was listed as "Ghost Riders in the Sky" in the European charts. So that chart had "Riders in the Sky" as number 7 of 1949 and "Ghost Riders in the Sky" as the number 33. When the European entries were changed to be the same as the rest of the charts the new chart placed the song at number 1 for the year.

The quality of the input data varies from one source to the next. As continual effort is expended to refine the data it is inevitable that the positions of some resulting entries will change (reflecting a higher quality set of results).
