The X-Family OST
As of 09/25/2007, there are at least 3 versions of OST on the market: 1) Preorder version 2) Taiwan version 3) Hong Kong version.
The difference between preorder and non-preorder version is the inclusion of the song Zui Ai Hai Shi Ni, which it's releasing right was obtained from another recording company after the preorder release. I'm not sure of the difference between TW and HK non-preorder version, as I only have the HK preorder version. The OST on Dramawiki is based on preorder version. --WaterOB 10:09, 25 Sep 2007 (CDT)
