Only watched series six until Lucie's exit, bar Stacey's performances online.
Only watched series seven until Aiden's exit.
Half-heartedly watched series eight. Can't remember much about it.
Stopped watching series nine after the farce that was Carolynne's exit.
Stopped watching series 10 after Melanie McCabe's exit, and judging by my top three in this series, I really did make the right choice.
Only watched a few YouTube clips of series 11; Fleur's are the only ones that held my interest.

Series 10:
Sam Bailey

(I can't remember particularly loving any of the others - only series I had no favourites really!)

Series 11:
Fleur East
Stephanie Nala
Stereo Kicks (thought they were one of the only boy bands on x factor who could all genuinely sing!)
.. And my guilty pleasure was Chloe Jasmine as I liked her different voice

Series 12:
Che Chesterman
Louisa Johnson
(Don't love any of the other enough yet for them to stand out for me.. I liked Seann and Alien but they've already gone so judging by that I probably won't be happy with the winner this year! I also wished Jennifer had got the wild card instead of Monica)

... Going back on a trip down memory lane for that I've realised I'm glad to be relieved of having any boy bands, boys who are only in the final for their looks and the token 'past it' act who would never sell records in the real world. Guess this year is a welcome relief in that respect. Next, it would be nice if they could get rid of all the screechy singers and stick to those with a nice tone to their voice for once! All the girls in this series sound the same to me really..
