No only rap in particular. Rap is particular is about words and lyricism. What sort of a random question eye- your question of itself proves why kpop fans shouldn’t talk about rap eye-
You can enjoy any rap you want. But to technically judge rap you can’t do so without lyricism. And that’s what everyone here is trying to do saying xyz rapper is better than so and so with no knowledge of the actual lyricism.
Its one thing if people were judging lyrics but they are simply judging flow and delivery. Its like how someone who isn't an expert at singing can tell who's a better singer than so and so because they might sound like they're, straining, out of breath etc. Delivery and flow are equally important in rap if it doesn't sound good no one is going to care what the lyrics say. In fact some of the most random lyrics can sound good if someone raps them properly. Most rappers out right now rap about the same ol thing yet they are regarded as good rappers not because of their lyricism but because of flow. Not to mention it'd be hard to base it off of lyrics anyway since a lot of idols don't write their own lyrics. So if we can't base if off flow or lyrics do we not judge rap at all?
