"I think stuff on the radio is mostly good, but it's just not what I'm into. I'm not into rap metal"

Jon Crosby's quote recommends that he is not a fan of rap metal, but he does think that the music on the radio is typically good. This might suggest that he takes pleasure in other categories of music, such as rock, pop, or country, but rap metal is not something he has an interest in. It might likewise mean that he is not a fan of the radio in general, however he still values the music that is played on it. He might also be indicating that he prefers to listen to music that is not mainstream, and rap metal is too popular for his taste. Whatever the case, it is clear that Jon Crosby is not a fan of rap metal.
