Everyone knows that _____ was the best year for pop music, when they were 16 (or 14 or 18) and when "______" was on the radio and MTV constantly. It's a scientifically proven fact. And now there's a website, where, thank god, you can relive the best pop music of your lifetime without even having to remember what it was. Simply hit up The Nostalgia Machine and enter a year. The site then loads up the music videos of the Billboard Hot 100 chart from the given 12-month period, so you can bliss out to the sounds of your youth while thinking of Johnny or Jane, your swoonable Junior Prom date, or whoever. We'll warn you that this might get a little addictive, especially since you can go all the way back to 1960. But that's the power of nostalgia for you. And as for the actual true best-ever year in pop music? Why, it's 1997, obviously.
