Consider really edgy compositions folk tunes? (7,5)

I believe the answer is:

country music

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

'consider really edgy compositions' is the definition.
I can't tell whether this definition defines the answer.

'folk tunes?' is the wordplay.
'folk' becomes 'country' (synonyms).
'tunes?' becomes 'music' (I can't justify this - if you can you should believe this answer much more).
'country'+'music'='COUNTRY MUSIC'

Can you help me to learn more?

(Other definitions for country music that I've seen before include "Emmylou Harris' genre" , "Dolly Parton's genre?" .)

I've seen this clue in The Irish Times.
