What is that weird noise in the mix of Sympathy For the Devil?

It's a tape reel. The source used by the radio station has too high a level of resolution

it was all through the song. 104.3 FM new jersey. 9 Pm .Creek tuner.right channell

i am on the computer and the powered speakers were right in front of me.. Oscillation like a theremin . You didn't here it on their led zep segment The same thing when they played that track the day before (they use the same source:fingerprint!)

it's from a deteriorating tape. Too many reissues. the new  digitalization is revealing the damage. Go to a classic( i heart) rock station and listen . You'll hear it within 3 

days!

only this station, this tuner, . other records reveal the same whine but it's under the music. No problems on WABC am!
