a lot of people like kid cudi, so anything by him (personally i only like some of his stuff)
living legends, nas, and kevin michaels. kevin michaels is more of a r&b type rap but is still good.
kendrick lamar is really good, he has some "hardcore" stuff but most of his songs are pretty laid back
a$ap rocky and joey bada$$ are also really good
just some off the top of my head, you could check out some of kanyes old stuff too
