No, 2 me, there's commerical rap and mainstream Hip-Hop. Mainstream Hip-Hop is Hip-Hop music that has decent promotion and has success with all audiences. When i talk about mainstream Hip-Hop, i talking about FP's Switch, LL's Control Myself, BEP's Don't Lie, Jurassic 5's Work It Out, etc.
When i think of commerical rap, i think of rap music that is made just 2 sell records, make money, and become famous. This commercial rap usually has no artistic attempts, creative lyrics, or even a talented so-called "artist." When it comes 2 commerical rap, i think of anything G-Unit, Young Dro, Young Joc, most of Bad Boy stuff, etc.
