There are some rappers, that 'rap' in Dutch. Most are not very good; some are less annoying and a few are really great.
This Bloedserieus character sucks big time, imo. (The broken leg you pointed out was Niels Kokmeijer, caused by Rachid Bouaouzan, who was prosecuted for the tackle.)
Better Dutch rappers include:
Gotcha - Je moet je bek houweOsdorp Posse - MoordenaarExtince - Spraakwater
