So I have downloaded many albums onto my PC and have synced them onto my phone. Yet in my music library there are a few artists missing and they're not in my albums either. I can only find the artist when I search for them.

So I have downloaded many albums onto my PC and have synced them onto my phone. Yet in my music library there are a few artists missing and they're not in my albums or any other category either. I can only find the artist when I look them up in the search bar. Why are not all of these artists showing up? I have tried deleting my music and redownloading but it still shows the same albums with quite a few missing.
