Whilst I disagree with one of the other reviewers who said that the music from the Specials was non descript, I have to agree that this is definitely better. The previous CD, taken from the Specials had loads of good tracks on, but some of it was a little too familiar.
This CD is full of new sounds. A new doctor, with a new tardis deserves a new score and Murray Gold has really delivered here. Plenty of variety and some really excellent themes. The opening titles have been given a tasty reworking and I love the new themes for Amy and the Doctor. Very memorable and evoke the TV series very nicely. There are many other tunes which capture the mood of the series but are just as good as musical pieces in their own right.
I used to think that the music for series 3 was the best, but I have changed my mind. If you only buy one Doctor Who soundtrack make it this one. However you really should get the others as well, as they are all good. Oh and while your about it you should check out the two soundtracks from Torchwood, you should enjoy those too.
