I feel sad that I have missed this for 10 years. WOW!

Your voice would calm a storm. Really nice :)

not even going to lie I've listened to this cover like 20 times. your pitch is on point.

My brother commented on this cover exactly 8 years ago. we are in the same songs at almost the same ages. I am proud to be like you my dear brother ;)

Wow! From Greece! Thank you!

her voice gives me goose bumps

Came here not sure that any cover of this song would be good. As soon as she stared singing though, shivers went down my spine. This is an amazing cover, and I can't get enough of it!

Outstandingly phenomenal.

oh wow....

Seriously, this is one of the best versions out. Whenever i recommend this song, it's this video i share :) Not only that, but your video has helped me to learn this song as well ^.^

before sleeping I listen to this version because relaxes me a lot. Ty great and beatiful singer

ahhh, your voice sounds so perfect! so unique and amazing!

Dont know how many times I've listened to this one. When my mood is going down under your version helps me out. I could say I really don't know why but I do. This is a good one. That's why. Thank you.

Beautiful voice and yet it still reflects perfectly the bluesy nature of this song.

What a divine voice and feelings !!! SUPERB !!! FANTASTICO !!!

No matter how many times I watch and listen to this it gets better each time. Great work.

Sweet and pure

Every now and then I listen to this song. It brings light to my world. Thanks. Emme Boo said it best in the commends: "This song was made for you! your voice Is unbelievable".

This girl has it all. A beautiful face and a beautiful voice. Pure and true.

Effortlessly beautiful!!! 😍

Wow her voice is mind blowing

Literally gave me chills

I am obsessed with your cover of this song, beautiful cover.

fantastic this is far the best little black sub cover on youtube 10/10

Just blown away by your version of this song. Thank you!

You know, there are many great female musicians out there, but very few play with such passion. From one musician to another, that's what makes this video so special. Absolutely great work Mackenzie! I hope to keep hearing more from you. :)

I have listened to the original song about 10 billion times and I have come to the conclusion that this song was made for you! your voice Is unbelievable and I wish you the best if you are/want to pursue a singing career!

Thank you for sharing, I cannot stop listening to this

Since I heard this for about three or four years ago I still sometimes go back to listen to your version of this one as I like it so much. Thanks.

Gran bella versione, voce splendida. Aggiungo alla playlist, peccato averla scoperta solo ora

Just amazing!

I've watched this video about 20 times. Scowered the internet for covers. This is by a LONG SHOT, the very best cover I have ever heard in my lifetime. It's a shame because no matter how good your performance is in your other vids, this will be better. This is pretty much perfect.

That was really good, loved how you were able to keep in tune with your guitar the whole time. This really motivates me to get that finger picking down. Awesome.

You have such a unique quality to your voice - it's so lovely! Love the song too. Kudos! x

blown away, this is amazing!

one of the best versions beside black k. :) beautiful!

Goosebumps. So many goosebumps. Rock on!

This is just great. My daughters and I have watched so many of your vids. Inspirational.

Really excellent cover of a great song! Thanks for sharing with us!

Miss, I am haunted by the beauty of your voice. Well done, and I look forward to more.

I just stumbled upon your video was not expecting for you to have such a powerful voice, your voice is amazing :)
