OK I live in U.S and I want to make forum about Asian music which I want to share music with other people. But I dun no if it that legal for me to put sharing music with other people ? Or what happen if someone else wants to share their music there I just open the forum and didn't post any music. By the way I have see a few forum are already doing this. Just wondering what is the chance I get caught and do I go to jail for that?

Music is protected by copyright. Its illegal to distribute such music without the permission of the copyright holder. Its unlikely you would be jailed, but being sued for big bucks is a strong possibility.
