"Since the PS3 launch of Sony's karaoke sim in December 2007, four million extra songs have been purchased online. And, brace yourself, this is what we've mostly opted for...

10 American Pie - Don McLean
9 Baby One More Time - Britney Spears (check)
8 Take On Me - A-ha (check)
7 Eye Of The Tiger - Survivor (pending)
6 Girls Just Wanna Have Fun - Cyndi Lauper (check)
5 Torn - Natalie Imbruglia
4 Suspicious Minds - Elvis Presley
3 Just Like A Pill - P!nk
2 Final Countdown - Europe
1 Total Eclipse Of The Heart - Bonnie Tyler"

In addition to the onces highlighted above me and my girlfriend bought some ~11 extra other songs so far (We got Singstar Vol 2). Whitney Houston (I wanna dance with Somebody), Kylie Minoque (I should be so lucky), etc.

"Own up, which new songs have you added to your SingStar library?"

4 Million!? WOW thats extremely impressive, I didnt think it was that big!

I think it's a very fun game, we mostly play the game with friends before going out. Goes especially well in combination with a few drinks.

Currently my kid sister borrowed it though.
