Hehehe, I know it's tough quesion, that's why I asked it :p
My default is Pardon Me but I too find it hard to truly narrow down. I love Nebula, A Crow Left Of The Murder, Here In My Room, Leech and Rogues too! Oh and Pantomime, but I can never decide which version I prefer.
Oh, and I'm glad you're enjoying M.A.G. The singer, like Brandon, has a beautiful voice and a wonderful way with words. Unfortunately though, they only released one album so for anything else, you'll have to look into his solo work.
