Appreciation i think OP's title is misleading both Tae and Jess are saying joo gotta sing. (1 Viewer)

Jessica is just really trying to be kind.
I am guessing unlike Wendy that girls vocals really lacked.

And Taeyeon telling Wendy to keep some mass.

also the contexts are clearly very different... jessica is a judge on a reality program, perhaps she was instructed to be the "good cop", so she's saying the same thing but kinder lol, taeyeon's in an interview so she kinda gets to be a little more direct about how she feels, cause it isn't addressed as feedback/advice to anyone in particular
