It,s a world thing not just Polish
No it is not a world thing. There are many other music which can be very interesting. I for one like Persian classical, as well as Indian Sufi ... and also American Jazz ... also Spanish Influences into music.
As for the "Black Culture" ... I think it would not be a correct statement, due to so many blacks into an entire separate continent of Africa (Central and South), and then Americas ... all have variations in their culture. I feel that the GANGSTA and the THUGGY or other forms of various names have a very negative image. No person with a decent mind, a good education and a healthy family structure would be attracted to such stuff. Among these people I would also include dignified and educated black folks.
Although I am not the man to really be able to say when it comes exclusively to blacks, because I never had the opportunity to know a black person up close or befriend that well ... but I have faith that not all can be into this Hip-Hop, thuggy, gangsta kind of thing. But as I said, through the media we know that most seem to be on this track.
Hence, whether they are into it or not, many aimless Polish youth with broken families, lack of values, or disinterested in education can follow such things. They may create a lot of noise, but the do not represent the whole of Polish New Generation in any which ever way you can think of.
