For japan, i'm big old fan of maaya sakamoto and mr.children (of course two different genres), but yeah already over 20 years. I know mackey very late (just about 5 years ago), around this single release, but actually it's not this song that i heard. That makes me new fan of mackey. Anyway his personal problems didn't bother me when we're talking about music and that happens with any artist i like. Greetings (salam) from indonesia.
I've been with japan music for 25 years more or less and heard thousand of songs (hundreds of artists). I can safely say he's one of the most talented music person in the j music universe.
