Yep. Same riff. I always found it interesting when bands would put their own unique spin on a song (Metallica - Master Of Puppets / David Bowie - Andy Warhol for example), and I'm totally fine with that. It's when a band completely steals a riff and acts like it was just a coincidence. It's clearly copies from SYL, but I always wonder who brought the riff to band practice.
I just imagine the band running through riffs and trying to write songs, and one of the guitarists plays a riff, and the rest of the band says "that's perfect", and the guitarist doesn't say "well, it's inspired/stolen from ______". And, because the guitarist wants validation from the band, he doesn't mention where the riff came from. Months later, the song comes up on the album, and all the rest of the fans are thinking "why did they copy _____".
True story: i was staring a band with a really talented guitar player from High School. I couldn't really shred yet, but I was a much better rhythm guitarist and writer then he was. We were trying to write a simple riff to bridge two other parts together, and I wrote a riff that just worked, and it sounded amazing! About a year later, Pantera released "Reinventing The Steel", and the exact same riff I wrote was on one of their songs. I was crushed at first because now everyone would think I tried to copy Dimebag, but after a while, I felt like if I was writing riffs like Dimebag was, I was on the right path.
Kinda funny.
