This is the most in recent memory. Simplistic, stunning, just a really good vocal and emotional.

Another one was Andy Williams Chasing Cars. He was absolutely beautiful, and I liked the version..

All of Rachel Adedeji's performances

Little Mix - I'm Like A Bird.

Nights in White Satin by that bloke who won last time, he shocked me and it was fantastic!

Most of paije richardsons performances.

Oh dear God that was awful

Distric 3 - Simply the best
Melaine - week 2 that performance

All of Ruth Lorenzo.....didnt make the final? ridiculous.....Love aint here anymore a particular fave of mine

And to think Cowell wanted her out in week two against a dull girlband (dull enough to actually call themselves 'girlband') who were bottom two in week one AND two.

Paije's "Stop"

Wasnt that the little 'Lenny Henry'?

Jedward - No Matter What.

Last night's White Flag by Jade Ellis needs to be added to this.

This. And 'White Flag' by Jade.

Daniel Evans' ones.

Paige Richardson- Let it Be

Probably one of the most underrated contestants ever. I loved Danni as a judge, but she had no idea what to do with him.

Rylan Clark - Gold.
Janet Devlin - MMMBop.
Nikitta Angus - Dancing Queen.

Seeing as she went out first I think it's fair to say Roberta from series 1, her performance was underrated.

Definitely this.

And also, Craig Colton - Paparazzi

JLS - Hallelujah

So poignant.

Nikitta Angus - Bring It On Home; Rachel Adedeji - Let Me Entertain You; Leona Lewis - Bridge Over Troubled Water; Ruth Lorenzo - My All; Stacey Solomon - Somewhere; Misha B - Dancing In The Street; Melanie Masson - Little Help From My Friends; Alisha Bennett - Say A Little Prayer, and most of all...

Treyc Cohen - Whole Lotta Love.

Definitely most of Paije, Treyc and Rachel Adedeji's performances were underrated.

Specifically I think that Jade's 'Love Is A Losing Game', Carolynne's 'Starships' and James Michaels' 'Ticket To Ride' were all very underrated.
