Yes, definitely. There may be some that don't but most do. But many Pentecostals do not believe in listening to any music that isn't about God, so they don't listen to country or rock or rap or anything like that. Again, not all Pentecostals believe that way, but many do.
I don't think so. To be Pentecostal means to believe in the Holy Spirit allowing people to speak in other tongues, and Pentecostals still believe that.
