I'm looking for several things in this thread.
Pop and rock music in languages other than English, regardless of the nationality.
Artists from non-English speaking parts of the world.
An enthusiasm for music and a wish to share your discoveries.
No holds barred. If Il Traviatore is popular, in your opinion, by all means post it. Worried that Abba only released music in English (apart from a couple examples). Don't worry. They're Swedish. Post what you like. Want to post U2? Sure. The official language of their homeland is Gaelic, so they qualify. Krautrock? Educate us. African? Tibetan? Indian? The list goes on. What's out there that you have heard?
