I just heard the Bootleg of DaD and its... decent overall. There are some good or very good parts, some strange pieces and a lot of underscore and electronic percussion in between. The Percussion didn't bother me as much, because i'm listening a lot to Drum & Bass or Breakbeat-Music and have no problems with hearing them in a Flmscore, although some cues could have been better without all the electronics.
For me, the music is something like a mix of David Arnold's Bond-Style and the Stuff John Powell made for the Bourne-Movies, but a tad more accomplished. The Score is definately better than Goldeneye, a bit interior to Tomorrow never dies and mostly not comparable to Arnolds' best Bond, Casino Royale.
