This is what we found on Wikipedia regarding the Morning Melodies:

Monuments and Melodies is the first greatest hits compilation album by American rock band Incubus released on June 16, 2009, through Epic Records. It was released as a double-disc set, the first disc featuring 13 previously released singles from the albums Make Yourself, Morning View, A Crow Left of the Murder..., and Light Grenades, along with two new Brendan O'Brien–produced tracks, "Black Heart Inertia" and "Midnight Swim".

The second disc is a collection of rarities including B-sides, soundtrack cuts, alternate versions, three previously unreleased songs, and a cover of Prince's "Let's Go Crazy". The album takes its title from a song that was originally released as the B-side to "Megalomaniac" and as a bonus track on international releases of A Crow Left of the Murder...; it is also included on Disc 2 of this album.
