Hm, I saw that last night. It's cool that they put up one of these "unreleased"/session songs, but it seemed like they coulda picked something better. While I'm not asking for Mercy (although that woulda been a good way to get it out, as I'm not sure it deserves to be a stand alone single), I have to think they have some better songs sitting around that Smile. That song never did anything for me, sort of the way Are You Gonna Wait Forever and Neon Lights were let downs imo.
Smile isn't on the actual CD release is it?
