I wasn't prepared for this one. Reacting to the official music video for "One" by Metallica.

Nothing prepares you for this video. Metallica ended up buying the rights to the entire movie. This is the greatest anti-war song ever written.

I love when people listen to metal and realize that it isn't just headbanging about nothing. There's love and sadness and anger and just everything laid bare in it.

As a Vet with multiple combat deployments and many injuries, thank you for taking the time to listen to this song. You’re a wonderful analyst. Best wishes for your future

When you know it's coming and you know she doesn't know it's coming and then you see her face melt. Perfect!

They played this live at the Grammy's, then immediately lost the first ever heavy metal Grammy to...Jethro Tull. Greatest travesty of justice in music history.

As a veteran and huge Metallica fan, this song brings tears to my eyes pretty much every time I hear it. I’ve lost friends and been disabled myself and I often wonder whether it was all worth it. I always come back to yes, but it’s getting harder with each passing day to come to that conclusion.

I'm 48 years old. I watched this movie long before I saw the video clip from 'tallica. When I saw the video clip ...I was lightstruck ! ! ! Amazing video concept .....great movie too! Goosebumps !!!!!!!!!

The song "One" came out on their "Justice for All" album in 1988. I was a 13-year-old boy at the time, and it resonated back then. Now hearing it again and watching it through the lens of three combat tours, it's all new to me. The most remarkable thing about your reaction video is the visible effort to parse things for analyzation. Instead, you had an overall visceral reaction to the music and video. It's been 36 years since its release, and it still hits like a freight train. This song hurts to listen to, and I'm glad you acknowledged the song and video's power.

This is why "One" is the greatest metal song ever written - it literally changed the music industry and blew the doors open for metal.

You don't listen to this song just for the vocals.... you listen to it for its entirety. The guitar riffs, solos, melodies, the drums, the vocals, the background movie. All part of a masterpiece. Top 5 videos of all time easily.

Everyone had a reaction to the first time watching this clip. Yours was like how we all looked. Epic song.

Poor girl definitely wasn't ready for this! Metal is more than a sound. It makes you FEEL. It can be a workout. Some songs are invigorating, some are a motorcycle ride through a thunderstorm. I love when I see the misconception realized. Great video ✌🏼

“He’s a product of your profession…not mine” that hits hard

Years ago on tour, this song was a 15-20 minute song. They would set off flashbangs and fireworks to make you feel like you were in a war. Then it would get dark and silent and the opening guitar would start. As the beautiful guitar would play, the stage was lit in color. As it got closer to the chorus and the drums kicked in with the "darkness, imprisoning me..P", the stage would go to a full black and white strobe light display so you would feel the contrast of the pretty with the harsh reality. There have been shows where once the song was done, I had to sit for awhile to regroup. There's nothing like it in music

This video swept the nation. I lived in Alaska in 1989 when this video debuted. It was their first. Metalheads were ready. We all loved it. Then moved to Texas that same year. Everyone loved it in Texas too. It introduced American Thrash Metal to the masses

I'm an old Metallica fan. I was feeling nostalgic tonight and was watching some old videos and saw this one in the sidebar. I've never visited this channel before. Seeing The Vocalyst's reactions to this song, her eyes changing, her face transforming with the music, seeing the emotional transitions happen, reminded me of why I love this song so much. Witnessing someone experiencing, for the first time, a piece of music that I feel was such an iconic part of metal progression... was awesome. This video is beautiful.

A lot of people claim the song is anti-war but it is actually about the pain , suffering and aftermath of war. Unarguably the best band in history!

It's so refreshing to see someone watching this 36 years later and really appreciating the beauty and sadness and artistry of this amazing song!! Thank you for this!

Blows my mind that some are just now finding Metallica!! 🎸

"He's a product of your profession, not mine" is one of the best comebacks in movie history.
