The last one is from somewhere 2016. Windows nightlies seem to be coming regularly... Something wrong with the build system?

Jep, the music scraper is broken indeed. And I can't find a nightly build for MacOS anywhere.

I've asked about this a few days ago (500 or so, see here: Nightlies for OS X) and it worked: one (1) new osx nightly appeared. So maybe that's the way to go: open a feature request, wait a few weeks and once in a year another nightly comes out for MacOs...
...or go for another tool. While I've to admit that MediaElch is the best looking of the bunch Mac-wise there are others out there which may do the job... ...some may even run via CrossOver.
