Music in purchased not showing up under artist

Question

Basically my problem is that I keep one playlist to sync to my iPhone, because I only have the 16gb phone and I have way more music than that. So one particular album (that I purchased on itunes) would mysteriously not be there when I search by Artist. I then found out that if I go into playlist, under "Purchased" sure enough there it was, but it wouldnt show up under my other playlist, even though I put it there.
So I went back to itunes, clicked on my iPhone, and had it sync to "Purchased" playlist in addition to the other playlist. Then I exited music and reopened it. Voila! There was the album, under artist where it should be.
Apple, please fix this. Stop putting my music around where I never told it to be. If I put a song on my iPhone/iPod, it should come up whether i search by Playlist, Song, Album, Artist, etc. This is so frustrating.

I found that I had to close and then reopen the Grove Music app after setting a specific folder/location on the WD My Cloud that contains the music files before Grove would actually populate the Albums, Artists, and Songs categories. One needs to make sure to point Grove Music to the folders containing the music via the "Change where we look" option, then click the Add Folder option (the plus inside a circle icon) on the "Build your collection from your local music files" dialog box. Its possible it may take Grove a while to catalog the files if there are a large amount of files. It might be better to map the music directory on the WD My Cloud to one's local PC and point Grove at the mapped drive instead. Here is an example. I don't have any music on my local PC at the moment. The albums found and listed are stored on the WD My Cloud. It should also be noted that the folder "Music" on the WD My Cloud is a private share ("Public Access" set to Off) that has the "Media Serving" set to On.  On a side note, its possible that when Windows 10 was installed it configured the network connection as a "Public network", or has has turned off "Network discovery", in which case it will block certain or all access to local network devices like the WD My Cloud. See the following link for the general directions/steps to switch from a Public Network to a Private Network which should allow Windows 10 to access devices, like the WD My Cloud, on the local network: How to change Windows 10 network type from Public to Private One can enable or disable "Network Discovery" by following the general directions in this link even though its for Windows 7: Enable or disable network discovery
