Seriously, how would Greatest Hit: Vol 2 be a stopgap. I don't know about you, but I own all the previous albums. I didn't even bother looking at GNR Greatest Hits: Vol 1; I knew it wouldn't give me what I wanted, which is NEW SONGS from GNR. I would have to say that this is going to work for the "everyday" fan, but for anyone who is reading this I don't feel it would do much good. Just get the damn album out.
PS: The only exception being Sympathy For The Devil, which I downloaded.
