What are some great contemporary songs for karaoke?

I need to burn some CD"s for songs to do karaoke to and I wanted to know, what would be some great songs for ppl to sing for karaoke? Make sure they’re contemporary, or at least songs that everyone knows.

Abba
Michael Jackson
Britney Spears
Elvis
Eminem
Meat Loaf
Celine Dione
Westlife
Girls Aloud

ect, ect

^^ the kind of music that everyone knows, propbably depends on the age of the people taking part, just have a bit of everything and im sure they will be happy (:

good luck x
