Observations about the top 20 Radio stations in Germany

Before I got access to the radio, I realized that there is a wide spread in the number of radio stations in Germany. Mostly, maojority of the radio stations are broadcasting all kinds of music, such as Hip Hop, R&B, techno, and some mixed music. Music is a part of universal culture. Although lots of songs don't make sense to me at all, i am still enjoying some of the nice rhythm and beats. As well as in U.S, most popular musics are also being welcomed. In my opinion, the German tastes of music are quite similar to Americans. Furthermore, I also found one children radio music which is broadcasting children's favourite musics.
However, Germany radio media differed from U.S radio on language. For me, both English and German are both my second languages. In my experience, I haven't heard an non-English voice on radio. But in those radio stations, I realized that they are broadcasting both English and German songs and talkshows. At this points, it can't be denied that German respect minority much more than U.S radio stations.
