If only THIS was mainstream, the world would be a better place.

I wish I could hear this on the radio instead of the majority of the rubbish that is out at the moment. Amazing talent singers, songwriters, musicians - I could listen to you and Sam all day with a smile on my face.... truly an honour to listen to you guys!!

Your voice and this song bring me such peace... You're such a balm to my heart, Casey.

Casey, you are absolutely incredible. Keep making original songs, you're such a genuine artist!

He sounds like a Disney Prince... Love Love Love

Your voice is like a gentle warm spring breeze after a very cold winter. Your writing speaks from the heart. Give the world more of your talent. I am a follower.

I was all happy because I was like, "Casey might have an amazing voice, but I still play piano like a boss..." Then I come and watch this video, you're really upsetting me with all this talent haha...ha :'(

I love how Casey is like a therapist for a broken soul with every single song. :) A voice that sooths a beast, a lyrics that heals a wound, a rhythm that calms a rage.

Honestly you have the most hauntingly majestic voice I have heard in a long time... Please don't stop making music.

so glad I found you and Sam Tsui...you are amazing singers and so poignant. Could listen to you all day! I found you because I was listening to Brothers 3 version of Safe and Sound and saw Sam's which lead me to your mashups and consequently you. Amazing. Thank you! AND THANKS TO KZfaq!

Something about this song just grows on me, the more I listen to it, the more I love it....

Casey....I started off my morning listening to your voice. This is becoming an everyday ritual! Your voice is so clear and so beautiful I get goose bumps each time I hear you. Yours is a gift and I thank you for sharing your gift with me. Blessings....Teresa

don't know why i'm felling as sad as happy while listening to this beautiful song... makes me thinking about how fast time goes by, how many love but also war there's in our world... i'm just one single human but with this song it feels like having every feeling of the world in my heart. thank you!

Once again your talent is undeniable. The beautiful voice once again adds piece to my day. These lyrics shows the beauty of your soul. Much Love and thank you for helping to make my day a happy one!

Lyrics just like poetry. Paints a tender, sometimes beautiful picture. And what a voice that is singing those words!!

You have one of the most beautiful voices I've ever heard. I think I could listen to you all day :)

The richness, quality and purity of his voice reminds me of Josh Groban. Simply beautiful !!!! Especially enjoyed his video with Collabro .

Saw you on the Thinking out loud/ I'm not the only one mashup with Sam Tsui and you are amazing!! I love your voice:))

Loving this! Amazing talent. Reminds me so much of Josh Groban.

Amazing! Could tell right off the bat Sam was the one doing the video! And i love the piano/ Guitar sound! Amazing song amazing voice! I want more!!!

My first new singer that i have discovered this year, beau of a voice. I have to have my music on in the house almost everyday, His voice makes me close my eyes that is how i know. I just know.

You caught my attention with the Mashup with Sam. Your voice is amazing but I was a bit disappointed to hear you sing a lot higher in most of your songs. In my taste your deep voice is much more soft and beautilful than the higher notes!

STUNNING!!!!
