You're telling me you don't hear the incredibly obvious and unnatural pitch correction in that YT cover? The arrangement is very basic as well - the guy who sent me those even agreed.
Bitter users are funny. Go back to ear school.
Speaking of unnatural pitch correction, there is plenty in Mandolyn Mae's cover. Sounds to me like someone just threw Auto Tune on there, set a key and let it do it's magic. Not saying she's not a talented singer but the production is terrible.
