You know, I used to react the same way whenever I found a similarity between works of various artists, but then I just thought to myself "I will accept the fact that there are thousands of artists out there who have no clue what other artists' styles and works sound like during the production phase, so it is not entirely their fault. I will also accept that the similarity could have been caused by influences and/or sample packs released on the internet regardless of the integrity and credibility and ethicality involved in copying someone else's work".
Really. No sarcasm intended. That's how I think right now.
I understand your concern, but I suggest we just move on. Thanks anyway for pointing it out.
You know what though? If tracks are somewhat sounding the same, it kinda helps me while DJ-ing to mash them up during a transition. Then the crowd would go like "woooaaahhh!!"

Just pointing out the brighter side of things here.
