Really cool video! Thanks for putting it up, brother!

I was just wondering, though, I know this is off-topic, but a brother on this board told me that all music is haram, yet there is so much music in these videos, and these videos are about Islamic prayer. Is this all a matter of personal opinion, or are there, in fact, some types of music that are acceptable and some that are not? I was told by the brother that all types of music are haram... So I'm confused

If someone can enlighten me, I'd appreciate it
