Arrange cards A-Z for Hungarian dance music (7)

I believe the answer is:

czardas

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

'hungarian dance music' is the definition.
The definition suggests a singular noun which matches the answer.

'arrange cards a-z' is the wordplay.
'arrange' indicates an anagram.
'cards'+'a'+'z'='cardsaz'
'cardsaz' anagrammed gives 'CZARDAS'.

'for' is the link.

Can you help me to learn more?

(Another definition for czardas that I've seen is " dance".)

I've seen this clue in The Globe and Mail.
