All off them, but especially the over-produced, trigger-loaded ones. There was a Brick (furniture store) commercial going during the holidays, actually I think the G8d forsaken thing is still running but with new lyrics (to reflect post-christmas deals), and their audio engineer went full psychological assault with the rhythmic bell ringing- it was so reverbed, chorused and post-processed that you couldn't make out any single bell tone as they were all bleeding into each other at a very high volume- sure, effective to SEIZE BY FORCE the subconscious cognition of the entranced viewer, but it quickly became (more of) an offensive assault of the senses. So irritating.
