“most annoying hold music” – Google Search
I’ll add to this Google search on the “most annoying hold music” by saying that Continental Airlines’ agency desk (where travel agents call and request help with pricing and ticking issues) is teh brain-sucking evil.
Its print equivalent would be saying “doot!” several thousand times, to a mindlessly peppy and very short tune. Thus, you hear the same short musical phrase dozens of times while waiting to find out from the agent if they can help you or not.
Sometimes, it’s a dog’s life being a travel agent.
That is all.
