game of thrones

I'm a little stuck... Click here to teach me more about this clue!

'fantasy tv series' is the definition.
I know nothing about this answer so I can't judge whether this works.

'new theme song for a' is the wordplay.
'new' indicates an anagram.
'theme'+'song'+'for'+'a'='themesongfora'
'themesongfora' with letters rearranged gives 'GAME OF THRONES'.

Can you help me to learn more?
