What can I say to a co-worker who sings at work and sounds horrible??

I have a small office I share with this lady. One of her "helpers" is a guy who comes in and when there is music on he starts humming loudly or singing and he doesn't sound good at all. I already have other issues with this person and am trying to ignore the fact that he even still comes to work but that awful singing makes me want to shoot myself.

Phew...for a second I though you were from my office talking about me!

talk to his supervisor.

he he, too funny. when my mom sings, i ask her "who sings this song" and when she answers, i tell her "let them"...

Tell him to shut the F-k up!!!
Lol eheh eh e yeah I bet you wish you could say that!
Maybe you could bring it up to your supervisor and chose to remain anonymous....

tell him not to give up his day job!

say you have a headache already and that is making it hard to focus and that there must be a dying cat somewhere that is not helping, then ask him to go and find it!!

This is annoying. The office yes can have music to help pass the day and ease the worries abit, but when a person does that annoying singing that ruins it all.
Talk to the supervisor or one in charge of the office and tell him/her what is going on and let the boss handle this. Explain to your boss that he is too loud and how this effects the proper office enviroment.
As for your other issues with this person, this will have to be cleared up soon because the longer you wait the worse it will get.
If one of your issues with this person is for example his way of answering you in a rough way while he answers to other nicely when greeting or picking or leaving documents, then he maybe does not like you or does not want to even talk to you. This you will have to talk to him apart away from the office and casualy tell him about how each one needs to have appropriate office manners due to the nature of the job and for the well being of getting the job done correctly and perfecty to avoid errors which will cause set backs in the office.

SHUT UP!

Your solution is simple: don't play music when he's working. If he's there and someone turns on the radio, etc., just say that the music has been distracting you and ask to turn it off.

It may not solve all of your problems with this guy, but he won't be singing to the radio any more.

I have no idea what you should do but I feel your pain.

Can you wear headphones maybe?
