I absolutely could not pick one, so here are my choices.
You Raise Me Up
by Josh Groban
Cover by Bada
My first pick was this cover by former S.E.S member, Bada. She did this performance just after her mother passed away, and she brought everyone in the the audience, and even the MC to tears.
Cover by Ailee
Second is Ailee’s cover of “Halo.” Ailee is AMAZING. She gave me goosebumps with this cover, after seeing this I became an instant fan.
