Why must people be so negative all the time?
Who says people are being negative all the time? Isn't your suggestion that people are a... (drumroll please) negative attitude of your own?
If you don't like the song or Ping then just ignore the thread and focus on something positive instead. All this effort people seem to expend nowadays putting things down or moaning could be much better spent on good things.
Like criticising ping in the hope that when Apple see the groundswell of opinion they'll either fix it or kill it and stop throwing good resources and money after bad? How is that not constructive?
Adjust your thought processes, think "How can I make the world a better place" NOT how can I spread negativity about something that I have no interest in or care little about in reality.
How does your gripe here about people griping make the world a better place?
Instead of coming here and posting things that don't add to the world, go do something nice for someone.
You may wish to attend to the beam in your eye before worrying about the mote in other people's eyes.
