Of the banned artists, this is how I view the artists with their final songs.
Sam Smith - left on a high note, because I actually liked both songs sent in.
Katy B - It was the best song sent in by her out of the 3 songs so she went out on a major high note
Lily Allen - Both songs were very funny so she left on a hilarious note
Beyoncé - Left on an overrated note, since apparently Haunted is one of the most popular tracks on self-titled. Oh well, glad she's out
Evanescence - Left on a great note.
Selena Gomez - Left on a decent note. The bonus tracks were the best ones available
Miley - Left on a good note. It was nice to see Miley represented with 3 different eras during the past three seasons (Drive from Bangerz, Right Here from Meet Miley Cyrus and Robot from Can't Be Tamed)
Alexandra - Her songs haven't really been outstanding. Fire and Between the Sheets were the other two sent in. I preferred them over her final song. They're all average at best, but it's ironic that the song that got her banned was "It's Over"
David - My favorite from him, so I'm shocked he landed in the bottom 3. For me, he went out on a high note, but it's a shame it landed me in a rocky position.
Hedley - All three songs that were sent in, and funny enough, they were all sent in by Filipino members, were good. Hiding Place is the second best, so they left on a decent note.
Fifth Harmony - Two bonus songs knocked them out. Actually, all their songs were bonus tracks. Brave Honest Beautiful was the best one though thankfully.
Lorde - Rib was the best song sent in during the messy round. So she went on some type of high note
Meghan - Bang Dem Sticks ranked highest so of course she went out on a high note
Shakira - The One Thing was agreat way to say goodbye to Shakira
Mikky - Watch Me Rise was the only song I liked by him so good choice before kicking him out
