Not going to lie, I'm glad it did not make the album. Shotgun is such a great live song that I really dont want to be let down by a studio version, a la Why I Am.
Hearing Why I Am live before studio got my hopes up tremendously, and I really thought Why I Am could have been one of the bands best studio songs to date. Its still a fantastic song, but a little underachieved IMO.
That being said, I really think Shotgun would have been in the same boat. A lot of people put that song on such a high pedestal that regardless of how it sounded, ants were going to be disappointed. The band felt as if it didnt fit on the album, and this was for a reason. Seeing how great this album is, I most defintely trust Rob's judgement in terms of BW's track listing.
I'd love a B-side though
