The Internet is a great place to find new music. At sites like youtube, dailymotion, and accuradio, you can find popular songs in other languages. Some foreign songs I like just because I don't know the words. If I am working, I can listen to them, and not and not lose my concentration by paying attention to the words. Others I like, because the videos are fun to watch.
This one is in Japanese. Some of the words are in English, which helps. It's a happy song, and the video shows the Japanese way to go to the Moon: first, give it an atmosphere we can breathe, then go! I talked about this song in the past.
The next two are in Russian.
Glukoza Nostra makes good videos for their songs. This one is a take-off of the Matrix and World of Warcraft. I talked about this group before.
I like to think of Valery Meladze as a Russian Tom Jones. ViaGra is an all-girl group. I talked about them back in 2007.
This song (German) was a big hit in the eighties.
Don't what they're singing? No problem! The song was popular enough that they released an English version.
