Those wondering how FF IV DS' ost will sound, thanks to TGS a taste of IV DS' music has been released on the internet. You can download it here:
MEGAUPLOAD - The leading online storage and file delivery service
This offers bits of the remixed of 'Theme of Love', the Overworld theme and the Prologue. (In 1 mp3 file)
I think it sounds great. Especially 'Theme of Love'.
