Yeah 170 sounds about right, but no way is it only 17 songs in the game; There's three distinct songs used solely in the first night in Onett. If you mean alot of the songs are variations then yes I agree but still--digressions aside-- Guanxi will probably have less than 10 tracks. Not really the same workload I don't think.
But regardless, wait for someonesomewhere's word on it. I think I've strayed enough from the topic .
