Well in my opinion, I always look at the brighter side of things. K-Pop is huge so it's no doubt that people will draw from how popular it is. So I don't see why we should make a big deal out of other artists sampling other artists. Isn't there a saying that copying someone is the best form of flattery? So big ups to BEG, 2NE1, and T-ARA for influencing others with their music! ^^
