The best songs on Tragic Kingdom were Don't Speak, Just a Girl and Sunday Morning. On Return of Saturn at least half the Songs are as good as any of those three; Suspension without Suspense is better than Don't Speak, Ex-Girlfriend is better than Just a Girl, and Bathwater is better than Sunday Morning. Then you have New, Comforting Lie, Dark Blue, Artificial Sweetner, Too Late, Simple Kind of Life, Magics in the Makeup - all of which are just as good as anything on TK.
Simply based on the number of 'classic' songs, this album is The Daddy. I recently made a compilation CD of the best of ND (and I have everything they've ever released) - 10 out of 19 songs were from this album.
