I once shared a space with a girl who played dance music quite loudly. I asked her to turn it down a bit and from her reaction you would think I had just kicked her new puppy to death.

The following few weeks were frosty, to say the least, and I ended up moving elsewhere.

Soon they'll be back to their antics playing maybe baseball (just kidding, sounds crazy right but so does playing soccer in the office). They're just not concerned about other people's productivity. The general point is that open-office floor-plan easily leads to distractions like these and can even lead to animosity between co-workers.
