An album released by a band that contains all of their songs you will ever need to hear. Greatest Hits albums do not count, as they are intended to give you all of the band's best songs.
This word is intended to be used only by people who have an interest in a band, but aren't huge fans of them.
Ex. Smash Mouth - Astro Lounge. All of their good songs are on this album, unless you are a dedicated fan (unlikely).
The Beatles are an example of a band without an Uber album.
Hey, did you hear about Drowning Pool's new album coming out? I hear it's supposed to be an uber album!
