TV and Radio used to function as a guide to new music. Musicians were picked up, their music were played and they got publicity. So we had a lot of musicians making many different types of music making a living. But they seems to have stopped doing that and became an advertisement.
We used to hear a lot of Rock, Hip-hop, reggae, techno and many more. A few decades ago, there was diversity. Now, all we hear on Radio and TV are idles and crappy J-POP and Nothing Else.
Top charts are filled with that sort of industrial music. The songs that designed to sell and make profit.Unless you are into that kind of music, there is no music show you can bear to watch. None.
If those music are a few among many, that is fine. But if they are pretty much "it", then we get a problem.
