Just my personal opinion, but I'd say if you recorded it off the radio, DO NOT post a copy for anyone else. It's one thing for a "radio" station to play it before it's out, but I'm sure the band would not want it passed around, even amongst us diehards. If they did, they'd make it available to us.
I know everyone's dying to hear it, but I'd hate to see this showing up on the download sites. If you have a copy, keep it to yourself.
Let's be patient - the album's almost out!!!
