I think it's most likely that it's a remix of 'wishing'
that would make most sense... BECAUSE:
talkin' 2 myself - Ayu is going crazy and has 2 sides
decision - Ayu doesn't know what to decide, because she is split it half
so.. she is WISHING to seek an answer. Besides.. they'll probably want to repromote 'wishing' in 2007
