This is a very good question with no correct answer. You could ask them not to sing along but that would result in you alienating yourself from your colleagues. Here are some alternative options for you: 1.
Sing along to music yourself, except more loudly and obnoxiously then they do. Perhaps intentionally muddle the lyrics up. This might provoke them into realizing how horrible it is to listen to someone do the same.
2. Claim that you're parents were musicians and that you have a hyper sensitive musical ear so that when you hear someone singing, or tapping near by, you're automatically disturbed and have to listen to it so that it's actually a distraction to you that severely cuts back on your functionality at work. 3.
Change your radio station to classical or atmospheric stations, creating a hum-free environment. 4. When they hum, always politely get up and shut off the radio claiming your head hurts.
If you repeat this enough times, they'll catch on. 5. Turn off the music ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
