Filter my Library on Apple Music
iTunes/Music manages your music library which you can access via various views. So if you add a track its artist will always show up in the Artist view, its album will always show up in Albums (and vice versa). The beauty of this is that you can choose to play all Madonna tracks by selecting her in the Artist view, or choose to play a specific album only by selecting it in the Album view.
Obviously this gets difficult to manage the more your library grows. I currently have over 40'000 tracks in iTunes/Music and found that it's much easier to manage if I use playlists to keep things in places where I find them again.
