Karaoke type game for Play Station 3 (PS3)

I got Singstar & it's not nearly what my daughter wanted in the way of available songs. No Katy Perry or Miley Cyrus.

I'm assuming it's got to do with licensing. She can sing a few Adele songs on Singstar, so I'm assuming Adele is on a label owned by Sony.

Anyone know of any PS3 games that have more of what a teenager would like?

If it's in Thai, a plus, but since Sony is Japanese & most of their stuff seems to be geared toward the American market, I doubt that's possible.

I also consider using the Singstar microphone with her 2006 Thinkpad. I checked and it does recieve audio from the mic., but I'd need to find a program to allow the karaoke aspect of it.

It's probably available all over the place on CDs in Thailand, but I'm in Falahngland.

I didn't have this particular type of project on my mind when I came over back in December.
