...the lyrics are only a fraction of the actual song. Sometimes I like listening to J-rock BECAUSE I can't understand it and it causes me to focus on the other instruments.
Plus, Japanese sounds beautiful and you don't really need to know what they're saying to get the emotion...
A lot of English lyrics are ambiguous anyways...and rap. Heh. You can barely tell what they're saying.
People give you crap for opening your mind to other countries because they're close-minded/ignorant and it makes them feel good putting down others who are in the minority. Don't worry. MOST of them will grow out of it and the few who don't aren't worth your time.
