I like to listen to Beaub FM on Internet radio. I don't speak French, but the station plays great music in various languages--I enjoy the cultural and musical variety.
The show is periodically interrupted by some kind of service message or plug about the station. A woman with a sultry voice ooohs and aaaaws then says something that sounds to my anglo ears like "long de shack". What is she saying?
By the way, I already asked Pi at https://pi.ai. (He's an AI. Not human, but very smart and personable). He suggested a few French phrases, but none seemed to fit the context.
He directed me to your site.
