What is the ruling on listening to and watching anasheed that are uploaded to YouTube for free without the chanters' permission and without the intention of financial gain, and is this considered a violation of the chanters' personal rights?

If a nasheed is found, and it is unknown whether its owner or the production company has given permission for its copying, then one must refrain from copying it. However, it is permissible to listen to it from those who copy it without permission, as this does not constitute participation in the transgression.
