This article explains how to use your library in Spotify, including how to use the feature in the Spotify desktop app, website, and mobile app.
How to Filter and Organize Your Spotify Library
Your Library lives in a sidebar on the left side of the Spotify app, and looks and works the same across the macOS app, Windows app, and the Spotify website. When you click or tap the heart icon on a playlist, song, or album, or follow an artist, it will appear in Your Library for easy access later. If you create a Spotify playlist, you can also access it from Your Library.
You can expand and shorten the Your Library sidebar, switch between list and grid views, and access a special search feature that searches just your library instead of all of Spotify. It also has buttons to display just your playlists, podcasts and shows, albums, or artists, and you can create folders to organize your favorite songs and playlists.
