Back in March Ottman was interviewed by Film Music Media
and it seems he wants to expand upon themes he did for X2 in DOFP. But it seems Singer may have had different ideas at the time.
Listen to the interview here (it's very insightful):http://www.filmmusicmedia.com/interv...viewjohnottman
Also, I came across something interesting on the site of The Royalty Network
, who are an "independent music publisher and administrator, providing licensing and royalty services worldwide to prolific songwriters, producers and artists".
It seems a very familiar Beyoncé Knowles song will feature in DOFP! Or was it just used a temp track?!
