Multi volume sets

You rip a multi volume set. Most of the time you get something like
100 forgotten sixties classics  – CD1
100 forgotten sixties classics  – CD2
Etc.

You want to combine them into one album.

WMP has a tag for the disc number (set).

For each CD you fill in the set number.
You make the album titles identical so they appear in the interface as one album.

The result is probably not what you expected.

They are combined but sorted by track, not by Disc Number /Track.

You can't select a column Disc Number in the interface, sorting by Disc Number is not possible.

If you want to have them sorted by Disc Number /Track you have to edit the track numbers manually. This is a horrible job.

This can be solved easily by using MP3Tag
