No idea if there will be a theme, probably not.

So what songs should each act sing to get into the final, they will probably have to be epic songs but not ones which have been done a million times

My predictions

Little Mix - TLC- No Scrubs, Sugababes- To Lost in You
Amelia- Janis Joplin- Piece of My Heart, Pink- Nobody Knows
Marcus- Otis Redding- Dock Of The Bay, Wilson Picket- Mustang Sally
Misha- Aretha Franklin- Respect, Sam Cooke- A Change Is Gonna Come

Would LOVE it if Little Mix sang these two songs!

What i'd like them to sing

Little Mix-Love the way you lie
Too lost in you
Amelia- Innocent eyes
Zombie
Misha-Try Sleeping with a broken heart
You know am no good
