Weird one this year because it was wide open for the first few weeks, and it has only been the last 2/3 were Marcus and Little Mix have became the big contenders, where as in previous series you usually have a good idea by week 2 who the favourites are.

I think:

Week 2 - Kitty - It's Oh So Quiet (closed the show)
Week 3 - Janet - Sweet Child O' Mine
Week 4 - Craig - Set Fire to the Rain (closed the show)
Week 5 - Marcus - Reet Petite
Week 6 - Amelia - The Show Must Go On (closed the show)
Week 7 - Little Mix - Don't Let Go (Love)
Week 8 - Marcus - I'm Your Man/Lately
