Description

I look at https://www.wikidata.org/wiki/Q534828 and the Primary Sources tool suggests http://www.last.fm/music/Tylman+Susato/+similar as a source. However the name Georg Forster doesn't appear on http://www.last.fm/music/Tylman+Susato/+similar by the time I was editing and thus doesn't work as a reference for the purposes of Wikidata.

If you want to reference dynamic websites like this, how about using achieve.org for more permanent links?
