Still composing swinging tunes (5)

I believe the answer is:

lilts

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

'swinging tunes' is the definition.
'lilts' can be an answer for 'tunes' (I've seen this in another clue). I'm not certain of the 'swinging' bit.

'still composing' is the wordplay.
'composing' is an anagram indicator.
'still' with letters rearranged gives 'LILTS'.

Can you help me to learn more?

(Another definition for lilts that I've seen is " Canned drinks".)

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