I think Danyl is the best performer on the show. He could also perform well as a guest on any other show. He was also invited to the states (just like Susan Boyle), but declined the invite to finish the x-factor...., now he's being torn apart by the likes of Cheryl (wannabee pornstar) and Louis (wannabee something).
Cheryl can't sing half as well as Danyl and that's her problem..., or is that she's met a guy who doesn't actually fancy her? She's being #### for some reason, and that's my guess.
Ear pieces, yes, why not.
