By now, from all I have heard, all the known leaks, Better is my favourite.
Still, it's obvious it's the kind of song that was built in a studio, it lacks the live feel old guns used to give me, a kind of danger feel. I think the new stuff is a lot more emotional, especially the singing, it's like there is an individual trying to say everything he is feeling, over-emotioned. Like in the song Better, at least on the 2:06 minutes I've heard, the vocal goes almost incessantly, only stopping on short periods, it dominates the song completely, it doesn't allow that much breathing space for the rest of the instruments, but it still stands.
