I dislike American music period.
Dunno why.
When this happened to me, I found that it was because I was sick to death of hearing songs about love (especially when you can understand the lyrics). I know, there are songs that are not about love in Western English-language music but at that point in my life I only listened to popular music radio. This was in the last few years of the cassette.
For me as well, this was much of the allure of foreign music. Just the unknowing of what the song is literally about adds a whole new interesting layer. Japanese and Nordic music in particular, where the lyrics almost become meshed into the melody as if the foreign vocals are instruments of their own. It's difficult to describe.. but all I know is, even though I don't understand a single word, every time I listen to Kaze Wo Atsumete it makes me sooo happy
I know exactly where you're coming from. I've been similarly drawn to Japanese and Korean music. I find that when listening to songs in foreign languages, I tend to hear the song for its composition and melodic harmonies which can oftentimes do a far better job of invoking emotions that words ever could. Too bad the more Japanese I learn, the less alluring it becomes
More recently I've been turned towards a lot of lyricless soundtrack music (mainly from image albums, OSTs, etc.) 95% of which comes from anime
Although, for the most part, the songs aren't blatantly Japanese.
