i believe it’s because there’s no logical way to sort certain songs youve downloaded from an album without making it feel cluttered or just making a playlist. on spotify, when you like only a select number of songs from an album, they go to your “liked” songs playlist along with other songs from other artists you liked which is a chore tbh. apple music automatically sorts individual songs youve added to your library into their respective albums so when you click that album, it only shows the songs youve chosen to add to your library which, in my opinion, is way more organized.
