I have to say that I've not listened to the new songs too much. I finally heard them live, and I liked them, but I'm not in love with them nor do i feel the need to listen to them all the time, like I did with the ROTR songs when we had those before the album came out.
I was wondering to myself why and I figured it out. The songs are very repetitive, a quality that she has not used in her writing since BNN. All her songs have been so lyrically driven in past albums; they tell a story and always move forward. I feel these songs lack some of that story telling and imaginative lyrics as songs past. I'm not saying they aren't good and have a complete lack of these things, just somewhat deficient. I'm thinking the album presentation of the songs will be more of a complete package with all the different techniques she's been utilizing lately, but it used to be that I liked the acoustic better than album! I guess I will see.
