I was recently in Peru where all they speak is Spanish. It is almost impossible to find anyone who spoke English except the missionaries. I did notice one thing: Alot of the music they listened to was in English. It was English rock, rap, and other types. Now the Bible says that we are to "abstain from all appereance of evil" (I Thessalonians) Now if you were to bring Christian rap or rock or contemp Christian to Peru the Peruvians would think you were listening to the real thing. I would have to say then that you would be sinning by listening to it because despite what the words say, the music speaks differently. Remember Music is the universal language.
