There's a commercial that plays on TV everyday now where in the lyrics 就要 is sung as
juo. 就要就要 is sung as
juo juo. There's nothing in my dictionaries alluding to a 就要 contraction and I've not been able to find anything online talking about it. My hunch is that it is just a rhyming technique to make the lyrics sound better.
The video can be found here: http://www.iqiyi.com/w_19rtxh9rel.html
就要就要 starts at about ~0:19.
Is this an actual thing anywhere?
