Just before
I'm With You was released Anthony said that not necessarily the best songs were used for the album, just the most cohesive ones. So we could be looking as some pretty good songs here.
I think they're on to something good here too. I wish more artists would do similar things; the label makes money and the fans get to legally purchase and hear all their fave's music. It's a bit pointless letting most of their material go to waste.
