For me the lyrics of songs are mostly irrelevant and it doesn't matter if I understand it or not. I usually don't pay attention to to it anyway.

That's exactly why I enjoy listening to foreign pop music: I cannot hear how vapid the lyrics are.

But besides that, great music does not need to spell it out to convey meaning and emotion.

If the appreciation of a foreign song keeps growing, I will eventually look up a few translations. Their mixed interpretation usually only enhances an already enjoyable experience.
