Number One Hits is my first Lips game. A lot of the achievements for the first game can be achieved with it, but some of them are not, so that is why the message appears.
If you want to do the challenge achievement just add me.. Tjippietjap, or my daughter Nena G
My daughter loves to sing "karma chameleon", "how you remind me" and "u can't touch this", but yeah.. she is 8 and dutch so you'll won't have to worry about winning :P
And me? I just love to have a challenge
