Can someone school me on Singstar PS3?

[bumidan]

I'm still looking at the song list for PS3 Singstar. If I can get 30 to 40 songs for pure Karaoke purposes (ie. no vocals), then I will get one for my parents.

So I hope they add some older songs - 60s, 70s and 80s songs

By the way, can you play the PS2 Singstar disks in the PS3?
