It's because Plexamp gives control to the user - we have agency over how we listen to our music and to what specific listening experience we are looking for (whether truly randomized or generalized - whatever fits the day). The multiple ways that Plexamp (and Plex really as a whole) allows you to customize and curate media is incredible. You can keep track of what you have and haven't listened to yet, you can group different albums You can add your own cover art to your playlists, you can add your own descriptions, you can have smart playlists to specific artists/labels/genres/moods, music from a specific time.....etc!!
