There is definitely a way to gauge the quality of art.
But even if something is bad, people can and will still like it.
It's a slim distinction, yet it does exist.
There is such a thing as having an unsophisticated palate.
When you're 8, you think McDonald's is the best food on the planet and your mother's cooking is meh.
When you're 25, you're trying to avoid McDonald's and you hope your mother cooked when you visit.
Music is no different.
If you really feeling this music out now, it's because of two things:
1. You were raised on it. If raised on crap, you will like crap. It's the person who likes Kool-aid more than fruit juice.
2. You have severely underdeveloped taste in music.
It's probably both.
