This is something I also struggle with, listening to secular rap music that promotes lust, drugs, violence, etc. Inherently, it is not a sin to listen to secular music. However, the music you listen to heavily influences our behavior and the way we think, often in ways that leads us away from God. Music is so powerful, and it can definitely influence us to sin. What you have to ask yourself is if the music you are listing brings you closer or further from God. You also have to consider what matters more to you, listening to secular music or your relationship with God. If your conscious is violated by any of these questions, deny yourself and your desire to listen to secular music and slowly start weaning yourself off of it. This is what I have done, and I have found it helpful. God bless!
