What is good pollution?

Pollution itself is a Word with negative connotation meaning to dirty the environment so there is no such thing as "good pollution".

However it can be used as in an ironic sense that you are going to pollute with a good thing. Let's say you pollute with something like music, if you play music (that nobody disagrees to) then you are spreading something into the area that isn't harmful, but rather pleasant. But the way it is spreading is like pollution, a form of parallelism of the spreading of both waste pollution and this "good pollution" making it ironic because pollution is bad, but you're spreading a good thing!
