I seem to be seeing a number of threads here that are being criticized for presenting songs that were sung by Germans in WWII.

If we are going to require that only the songs of the winning side in a conflict are studied, perhaps we should remove a number of traditional songs from the DT, as they were sung by the losing side.

I do not have to support the sentiments of a song to be able to appreciate that it meant something to those who sang it, and possibly like the tune or structure.
