The old saying goes

Music is a universal language because everyone can understand it, they don't have to know a language to be able to understand whats happening, like ifyour listening to a song in Japanese, you don't need to know Japanese to understand that its music.

Music is universal in more ways than one. Yes, it may be true that you can't understand what they are saying, but everyone can feel a beat. Certain chords played together make you happy, sad, calm, pumped, and even want to dance. I think that is why it is so therapudic. No matter what the language is most people know the type of music being played because of the reactions it receives. I can also say that language doesn't matter. On my trip to China I attended one of the churches. Amazingly they sang the same worship songs we did here. I was singing in English and the guy next to me sang just as much in worship in Chinese. It was the neatest experience. Don't get me wrong, it is always possible to interpret a song incorrectly. You may feel a certain reaction from the music when the words are saying something completely different, but the majority of the time it is what you feel in the rythm.
