I recently downloaded a music compilation CD containing 100 lovely songs.
When imported into my Windows 10 Groove Music application, instead of a single album with all of the songs contained, I was presented with one hundred songs separately!
A quick look at one of the song’s Metadata information, showed that each song had the singer listed as the Album Artist, instead of Various Artists.
By going into the CD’s folder and selecting all of 100 songs at once, I could change the Album Artist information simultaneously to “Various Artists.”
After doing this, my computer re-indexed the CD’s folder and I was presented with a single Album with all of the 100 songs contained.
