I personally find the original Japanese version of '1000 Words' kind of annoying. The song itself is fine, but Ms Koda's habit of making her voice crack on every second syllable is like a cheesegrater on my eardrums. Jade's English performance may be more 'generic', but I prefer it by a wide margin.
I like '1000 Words' and 'Suteki Da Ne?' about equally, I guess. Charming songs that suit their respective games well.
