There's a lot of variety in the content of hip hop. There's introspective hip hop from Black Star, sci-fi from Deltron 3030, liberal politics from Blue Scholars, storytelling about innercity life from Capital D & The Molemen, clever wordplay from Binary Star, or music from Jurassic 5 where the words are like another instrument so you don't have to worry about what they mean. If there are a few songs that you like, you can probably find more like them.
