Trendy list broadcast in a loud way (10)

I believe the answer is:

stridently

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

'in a loud way' is the definition.
I can't tell whether this defines the answer.

'trendy list broadcast' is the wordplay.
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'trendy'+'list'='trendylist'
'trendylist' anagrammed gives 'STRIDENTLY'.

Can you help me to learn more?

(Other definitions for stridently that I've seen before include "How some protest" , "In a loud, harsh way" .)

I've seen this clue in The Daily Express.
