It’s bad enough when you’re listening to headphones and I can hear your tinny beats from 10 metres away, but what’s even worse is when I encounter a sociopath who somehow thinks it’s okay to play their choice of music on a speaker in a tram/train/bus when it’s standing room only. I don’t inflict my shitty taste in music on you, so don’t do it to me! Rant over (if you ever get me started on this topic in person, it won’t be over).
