I have thought about this before, but in a slightly different way.
I like to show off STP's versatility, and while a GH CD sort of does that, I often think about what non-hit songs I would put on a CD. It would be assumed that they already know the radio songs (Dead & Bloated, Sex Type Thing, Wicked Garden, Creep, Plush, Vasoline, Interstate Love Song, Big Empty, Unglued, Dancing Days, Big Bang Baby, Lady Picture Show, Trippin' on a Hole in a Paper Heart, Down, Sour Girl, Days of the Week, Between the Lines), or that the disc I describe below would be a supplement to the songs I just listed.
I'm thinking it would HAVE to be a double disc:
Where the River Goes
Still Remains
Kitchenware & Candybars
Tumble in the Rough
And So I Know
Art School Girl
Adhesive
Seven Caged Tigers
Sex & Violence
I Got You
Atlanta
Wonderful
Hello It's Late
Too Cool Queenie
Long Way Home
Huckleberry Crumble
Hickory Dichotomy
Cinnamon
First Kiss on Mars
Maver
Bonus Tracks:
Love Machine
Dirty Dog
Lady, Your Roof Brings Me Down
Man I Didn't Know
It Doesn't Seem to Matter
Goodbye
