I'm not sure why you want to put the songs on the harddrive. If you want to call them up and sing to them using a karaoke player like Microstudio here's something to think about
:
Microstudio is really not a good player. It's OK to test things with, but it has limitations, not the least of which is disc internet info (You have already been advised to buy Hoster)
You can use other software that will create condensed songs for harddrive storage, they may even identify the songs for you.
If you want to be able to create a song label or jewel case insert, etc. you can get the song info and download the songs as non-karaoke, create the labels and use the label for karaoke discs that you may create (If Microstudio used disc information service, then there would need to be a label creator that labeled a disc created using cdg or bin files, so logically we would be asking MTU to do two things for us)

Good Luck
