I think if they have a excellent writer, an awesome director and an bad-ass cast... they have a chance. As for the new songs, I don't know if you know about this but in the 90's, I came across a CD that was titled: The Rocky Horror Picture Show: Songs From The Vaults Soundtrack. This outstanding CD had songs that were meant to be in the movie but was left out (for some crazy ass reason). I can see them use a few of these songs in the remake, if it was done right. If they use songs from this album, they have a greater chance.
