A video would be good for Sober.She should give that song a 2nd chance.Remember Pink's Who Knew & U + Ur Hand?They didn't do well the first time round but hit the top spot when re-released.
and Hey There Delilah was released last year but just became the #1 hit this year.
Maybe...she should release One Minute first then re-released Sober.It might work though.
