Library - Songs?? Like instead of Adding?

Is there no longer the option to view my entire library of songs on the desktop app? I can only see my "Liked Songs" under my library on the desktop app but I don't really use the "Like" functionality. I've always used the plus sign to add to my library, but it's seems like it's being removed from its usual places. It also seems the heart and the plus sign are interchangable in some places but not others. Hitting the heart for an album on my desktop while viewing an artist says it adds the album to my library yet hitting the heart on individual songs does not. I think I'm saving things but I'm liking them or I think I'm liking something but saving it? My big thing is I like to save things but that doesn't mean I necessarily like them. I generally reserve likes for things that stand out for me. I've attached a screenshot where it shows that I've liked a song but the heart on the album says "Save to your library." The three dots for the album will also show an option to save to library but the dots for the song do not. Additionally, searching my "Liked Songs" for an artist might show up nothing (because I haven't been using it) but going to the artist in my library will show the songs I've saved and hearts on them. I can unlike the songs but they were never in my "Liked Songs" to be begin with.

Edit: If I remove the hearts, it'll still say the song is in my library. However, checking all my songs on my phone only shows the songs I've "liked" but not the songs that fall under the albums I've saved. Does saving an album no longer save the individual songs to your library? Do I have to make playlists for each artist if I wish to listen to all their songs across all their albums? 

AHAHAH I'm so annoyed my morning is ruined
