I like Spiderweb better than Undone, but isn't it being on the Deluxe version only, kind of problematic? That's why as much as I think Spiderweb has the most mass appeal potential, pushing it would mean the sales for the regular album would disappear...
I would think they would use a song that was on both the Deluxe and Regular albums to help both albums' sales.
If not "Oh My"...I've been championing "Now That You're Here" since I heard it live in Spokane, it's a great upbeat 'summer' song
If the second single hits (probably "Oh My" ), then they could probably think about releasing "Spiderweb" for a one two punch. (then Undone)
