Hypnosis Microphone is a series about guys fighting by rapping.

There's a game, manga and anime for hypmic. The manga and drama tracks are the only canon media I'm aware of. The game and anime aren't canon but they are still really fun and interesting. Since this is a series about guys rapping there's a lot of music. Perhaps you are recognizing a pattern of me liking series with music involved. I've read the manga up until a certain point, until I gave up. I'm not as into hypmic compared to enstars, however I still enjoy it!

Hifumi Izanami, Dice Arisugawa, and Ichiro Yamada are my favorites!
