Andrea
"Cry Me a River" by Justin Timberlake... he'd probably take too long to get through the words LOL but it'd be something relatively contemporary for him to shine on
"Crying for no Reason" by Katy B (yes ok i'm on 'cry' on my itunes atm)
"Stay With Me (Baby)" by Lorraine Ellison (this is probably the best 'SCREAM INTO THE MICROPHONE OUT OF DESPERATION' song imaginable)
"Fighter" by Christina Aguilera (here for rock-diva andrea tbh)
"Who Knew / Try" by P!nk

Fleur
"Somebody Else's Guy" by Jocelyn Brown
"Finally" by CeCe Peniston
"Doo Wop (That Thing)" by Lauryn Hill
"Bootylicious" by Destiny's Child (complete with her saying CHERYL... can you handle this... MEL... can you handle this etc.)
"American Boy" by Estelle (must get Kanye to perform with her on the final though tbh)

Ben
"Never Tear Us Apart" by INXS - this would probably seal the crown for him tbh, it'd be such a perfect choice
"Iris" by Goo Goo Dolls - another pretty obvious song that everyone in their right mind loves
"Feel" by Robbie Williams
"All Time Love" by Will Young
"What's Up" by 4 Non Blondes

Lauren
"Fidelity" by Regina Spektor
"New York" by Paloma Faith
"Only You" by Yazoo
