X Factor UK: 10th Anniversary Mash-up!

It's X Factor UK's 10th Anniversary and it was pretty cool of them to come up with a mashup of songs from their successful alums: Leona Lewis, One Direction, Cher Lloyd, Little Mix, Alexandra Burke, Olly Murs, James Arthur and many more. Why didn't American Idol think of this before??

As you all know, the last time I posted something regarding X Factor UK was when Matt Cardle won the show in Season 7. Yes, I still follow Simon Cowell's little show, but I refuses to write anything about it because I just don't have enough time. This is their 10th year however, so why not? Enjoy!
