I do, but only stuff with no vocals. I can't concentrate because I'm bound to want to sing along Although when I'm programming I can listen to anything, and I usually end up listening to Björk or Fiona for a few hours straight.
In school, yes but only instrumental soundtracks (Memoirs of a Geisha). I only listen to music with vocals when I'm skimming through or writing but never to study!
I listen to music while I do my homework, but not when I'm studying for a test. Maybe some in the background, but usually nothing. It can be distracting.
No, I cannot do that. I will literally just sit there and sing a long to whatever I'm listening to and if it's up-tempo then I will get up and start dancing. So no work would be completed
When it's something really complex that requires a lot of thought, then no. However, if it's something like reseaching or typing up an essay, then yes. You can always come back and edit things later. It's a gradual process.
