Singstar opinions?

[Groundhog]

It's my girlfriend's birthday today and I'm struggling for ideas on what to get her...

She bought a PS2 and Guitar Hero a month or so ago and loves it, so I was thinking of maybe picking up Singstar for her. Is this game comparable to Guitar Hero on the fun scale?

I played the PS3 version at E3. Seems like it could be a winner on the Guitar Hero scale, but would definitely skew towards younger and/or female audiences.

Well, I just plonked out the cash for it, so I hope she likes it... cuz I know I will ;)

I got the SingStar rock edition. It's a very nice selection of tracks overall, with some Australian rock songs substituted in for our release.

Broke this out last nite and it was good fun, though would be much better when combined with alcohol and more people.

BTW, imagine if a company mixed Guitar Hero, SingStar, and one of those drumming games the have in the arcades in to a single game? How awesome would that be?
