How about, "I think you should sing solo -- so low no one can hear you!"
For the male who can't, there's, "I think you should sing tenor -- ten or twenty miles away!"
(It occurs to me that your chosen screen name is a bit musical so maybe those are old jokes to you. If so, sorry!)
More seriously, if she's doing it while people are trying to get work done, a talk with the boss about distracting behavior might help.
@AriaDiMezzo Once upon a time, I could sing. I now wouldn't inflict my voice on anyone, not without a shitload of practice. :)
@billblake2018 I can't sing worth a damn. It's the thing that's always held me back in music, due to the difficulty finding reliable singers. :(
@AriaDiMezzo That's one of the sillier prejudices about music. Fortunately, I grew up with classical music so I know better. :)
One of my bigger beefs about some pop is that there'll be this instrumental intro and I'm like--this is a whole damned symphony if only you'd let it go! But of course, there have to be lyrics and in just a few seconds....
What style of music do you do? (I'm short on bandwidth or I'd download and listen.)
Liberdon is a Mastodon instance for libertarians, ancaps, anarchists, voluntaryists, agorists, etc to sound off without fear of reprisal from jack or zuck. It was created in the wake of the Great Twitter Cullings of 2018, when a number of prominent libertarian accounts were suspended or banned.
Mastodon is a decentralized "federation" of community-run Mastodon servers which are part of an even greater federation called "the Fediverse". No matter how many users are on the instance you join, you can still follow and interact with the millions of users on any other instance throughout the Fediverse!
This is a primarily English-speaking instance, although everyone is welcome.
