While playing a song in a playlist, clicking on the album art next to the song name will bring you to the song in the playlist, if you're using the desktop client. Doesn't work on mobile. Clicking the song name will send you to the song in the album.

It's similar (well opposite) to Github commits view, where clicking a user avatar will send you to his profile, while clicking his nickname will show you all his commits in the current repo.

It's not a very good affordance.
