Anonymous Jew, it’s really not the same thing.
The radio show you’re referring to is presumably not marketed specifically for people in availus. It’s geared to a varied audience, and everyone needs to make their own decision as to wether or not it’s suitable for them.
The shows Moshe from Midwood are discussing are different. They are produced with the specific intention that they should be viewed on Tisha B’av. Any type of music seems inappropriate in that setting.
