Thanks, I changed my privacy settings to not have tailored ads and I haven't heard it once today! Granted I have been off work for 2 weeks so haven't been listening to Spotify as much, but whether this solution worked or the ad just came to the end of its run, I am happy to not be hearing it any more. Thanks for the help!
I'm having a similar problem with a different ad, something about Reese's I think? It's an awful ripping noise followed by some guy saying something really quick. Whenever I try to listen to music while falling asleep this ad keeps waking me up and freaking me out.
