i've tried it before...but unluckily,the service is only available to taiwan citizans,hk citizens can only be a trial member for 1 day(24hrs),after that you can no longer enjoy the service unless u use another e-mail address to register.
u have to dl the software first ,then u can listen to the whole songs,but u can only listen to the songs through the software.u can also dl the sings to your pc for next time's use(just for the sake of concenience).
