Are rap battles a thing here?

I see a lot of rap battles going on, about serious topics too. How would one even win those?

I personally like that music battles where people pick a genre and try to pick the best songs. In the end of the day, it's subjective to what the person likes. I feel the rap battles are the same. I personally don't read them bc they are too long, i lose interest when there are too many lines. However, if someone was damn good writing lyrics in a concise manner... i'd probably be interested in reading it. But what i've found so far is that i usually find them to be a tie... when it comes to my style, i haven't seen anything stand out. I'm a musician so my bar is kinda high. So, i tend to stay away from them unless i see something that stands out... but, of course there is a little subjectivity there too in what i personally would like to see. 

yes they are kinda a thing
