The bonus track Careful What You Wish For is pretty good. It has a reference to people going back and rating his albums way higher way after they come out and how even though people shit on Encore they'll change their minds and decide it's amazing. He's right too.
It's Charmagne Tripp http://www.charmagne.net/ http://www.myspace.com/charmagnetripp It was originally reported that Dina Rae was the one singing in the song but that's been reported false.
Careful What You Wish For is amazing! Deals with a number of issues, including the drug problem. If he rapped about his addiction the way he did here, I think Relapse would have been a much better album. My Darling is pretty good too minus verse 2 & 3. The deep voice effect kills it.
Careful What You Wish For is probably the best song that was recorded for the album. I don't understand why it didn't make the cut.
