The reply from forum members may be inconsistent, spotty and at times delayed. If you are looking for a quicker and ongoing stream of responses, I recommend you join one of the more popular social networks where they have fan pages and groups devoted to Punjabi media, like songs and movies. There are literally dozens of them on social networks. You would have a steady stream of "friends" too.
The other aids. Search You Tube for "channels" on this topic. Then set up a You Tube account, and subscribe to the channel. YOu will then get an email every time new videos are uploaded.
Final suggestion. Search on Google for Punjabi cultural groups, networks, blogs to see if they have forums on this subject.
Probably you will get more feedback to your liking more quickly.
