I guess so, but for me, it's against people I truly don't believe are deserving of their attention or whatever it is they are receiving.
I root for deserving people. A talented person wins a Grammy, I praise that,
whether I actually like their music or not.
I'm annoyed if they beat someone I like better, but... I don't begrudge them their prize.
Untalented people getting #1 hits, or winning awards... people who have proven their inability to sing without auto-tune... it's annoying, and I can't help but diss them at any opportunity. Some people have called that jealousy. I just think I'm severely annoyed at injustice and knocking them down a peg is merely knocking them down to where I honestly feel they belong.
But yeah... I guess that's the textbook definition of "jealousy."
It doesn't just apply to music. Music is just an easy example. Any situation where someone is simply not deserving... it irks me.
