Sorry, people are going to hate me for this, but I really really hate Jessie J. Her performances are just so cringy, her songs are extremely annoying but it is mostly her facial expressions and body movements that make me feel sick. Everyone I've ever met loves her and I just don't see it.
As for Adele, I think I might be the only one, yet again, to find her boring. Her voice sounds average to me and the songs aren't that catchy. Well, she's no Beyonce.
