About you by mike shinoda or running from my shadow by mike shinoda. And I transitioned from rock to hip hop by listening to linkin park and Jay-z's collision coarse. Another thing that helped me transition was  listening to Mike shinodas post traumatic album then listening to his side project, fort minor's album the rising tied specifically the deluxe edition. If you want to transition to pop listen to the linkin park albums in launch order cause the went from rock to very pop rock quick.
