Yet it does.This doesn’t answer my question
Until the sale closes, CMG owns it.
The station is voice tracked. That means the log was created last week or earlier, and the tracks recorded before you hear it. All while CMG owns it.
After the sale closes, the log they play and the voices you hear may have been created prior to closing. Or not. It depends upon how far ahead they made logs. Usually you crank out Saturday, Sunday, and Monday's logs on Friday.
Who paid you for your work is dependent upon when you created the content, not necessarily upon when it aired. The creative work you did prior to the sale is an asset being conveyed to the new owner. You're being paid for making the stuff when you make it, not when it airs, unless you are making it live.
