Friday Musical Interlude - Reaction videos

As a change of pace, I thought I'd include something that I've started watching recently: people reacting to music videos for songs they have never heard before. It falls into a couple of categories from what I've seen, either people stepping outside of their own genre of musical tastes or younger people reacting to older songs they've never heard before.  It's interesting to watch, especially when they are surprised they love their discovery.

Here are two reaction videos from WeeabooReacts.  I'm starting here because his reaction videos were the first ones that made an impression on me.  I don't recall but one of his might be the first reaction video I ever saw. 

First Fleetwood Mac's Dreams and second, Van Halen's Eruption guitar solo, in a live performance.  Warning - he swears a lot, but the reactions are priceless.
