Oooh, can you share your playlist?
I Am The Doctor is incredible, and I think is the most exciting and most “Doctor Who” song there is. It just makes me so happy.
The Doctor’s Theme - I love a theme with some angelic singing in it and every time I hear this song I get chills.
Clara? - The Doctor puts it best:
CLARA: Is it a sad song?
DOCTOR: Nothing’s sad till it’s over. Then everything is.
And as Ashildr/Me says, “It was sad, and it was beautiful.”
Doomsday - 
Thirteen - this is great, it really goes for it! Very powerful, and more singing.
The Enigma of River Song - I can’t resist anything to do with River. Love it.
A Good Man? - I agree @TheLeo that is also a great one. Love the ticking sounds, very time traveller ish. Even if the title does remind me of my least favourite part of Capaldi’s series.
Song For Ten - A little cheesy, but since I first paid attention to the lyrics and applied them to Series 2… Now it’s a sad song for me!
I could go on. This show has such good music.
