to do 2017-09-08: Verify the artists selected for the added CDs 1,2, 4 are correct.
Merge recordings if needed.
Many of these recordings are so widespread they have pages of recordings to merge on the artists' pages. I started merging some. A lot more merging is needed. Just go through each artist and find the dozens of duplicate recordings. Make sure none are live and times are close, then merge them.
