If I'm allowed to have an opinion on this, i think its been taken down because certain people here don't like German music from 1933-1945 so the copyright excuse was used to take it down. Can you explain to me what copyright issues there are with music from 70 years ago by artists that are virtually deceased and would also want their work to be heard by others? Since the music is from mid-ish 19th century you'd have to supply me with copyright rules from 1933-1945 period in Germany where it claims it can't be used in video games for entertainment or enjoyment purposes. Otherwise I my opinion remains what it remains.
