I realize this might make me sound curmudgeonly, but here’s what strikes me as a needless source of annoyance: Hold music with vocals.
I’m fine with being put on hold occasionally, but I want to be able to work effectively while I’m waiting. That’s considerably harder, I think, when the hold music has vocals, rather than just unobtrusive instrumentals. The job of hold music should be to make callers feel confident that their calls haven’t been disconnected — not to entertain. Just some officious advice, hold music decision makers, from your friendly neighborhood blogger.
Also: Kids these days. Grrr. O tempora, o mores.
