I don’t know about all time, but…

• Visigoth - Revenant King - the intro and all the variations on it throughout the song
• Eternal Champion - A Face in the Glare
• Unleashed - Midvinterblot - I know it’s super basic but it gets me amped up regardless
• Opeth - Serenity Painted Death - Already mentioned but damn

Oddly most of my favorite stuff - like prog metal - I tend to not like a particular riff from.
