Lounges with uplifting music opening lots of whiskey cocktails starting off (8)

I believe the answer is:

parlours

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

'lounges with uplifting' is the definition.
I can't tell whether this defines the answer.

'music opening lots of whiskey cocktails starting off' is the wordplay.
'music' becomes 'a'.
'opening' is an insertion indicator (some letters open a gap in others).
'lots of whiskey' becomes 'prl' (I can't explain this - if you can you should give a lot more credence to this answer).
'cocktails' becomes 'sours' (sour is a kind of cocktail).
'starting off' means to remove the first letter (the starting letter is removed).
'a' going within 'prl' is 'parl'.
'sours' with its initial letter taken away is 'ours'.
'parl'+'ours'='PARLOURS'

Can you help me to learn more?

(Another definition for parlours that I've seen is " Rooms".)

I've seen this clue in the Irish Times.
