Why is 音乐 plagiarism so common?

Either they ran out of ideas, 或者 they want profit. Most artists 你 hear on the radio these days are all the same:

-Generic lyrical themes (party, love, sex, fun, etc...)
-Autotune
-Uses different noises to fill the emptyness (unh, oh, huh, yeah, mmh)
-No originality
-Praised 由 millions of young kids/teens that don't have a single clue what actual talent sounds like
-Alot of them lip-sync at concerts

At the end of the day, they could care less about quality and legitimacy. As long as they're making profit and being praised, because that's all they care about.

Because they are lack of creativity and too lazy for making their own music. Also, to gain money with easy way.
