My favorite would have to be H&T, closely followed by BNN.
-Heroes and Thieves is pretty different, very lighter, but it's truly amazing! This was worth waiting 3 years for!
-BNN is just full of darkness, but also has those lighter songs too, and i love the album art. all the songs are so close to my heart.
Harmonium fans please don't shoot me for this:
Although, i love Harmonium for it's organic-ness, and it's bittersweet songs, but there's something that i felt was missing. it's still really good, just not my favorite.
