I personally think that the next album should be called "Space Needle." The lyrics seem to fit nicely for an artist who has matured and seen alot of the good and bad of rock 'n roll (of course, it all depends on what theme Stevie decides to go for, ala Shangri~La).
Here are some songs that I would love to hear:
Space Needle
Lady From The Mountain
Sanctuary
The Dealer (with Tom Petty)
She Loves Him Still
All The Beautiful Worlds
Mistaken Love
My Heart
Another idea - Stevie mentioned in the "Ask Stevie" answers that she would like to see remastered special editions of Bella Donna, The Wild Heart, etc. put out possibly next year... I would love for demos like The Dealer and Julia and Belle Fleur to be included. Casual fans (and the mass market) could then get some history of these demos as they hear them, as well as some new versions, for the first time. For example, Planets Of The Universe, from TISL and Rumours Remastered. Wouldn't this rock everybody and everything?!
