I had this same feeling the other day when I saw "Now That's What I Call Music: Volume 55". Fifty-Five!? I remember when the first CD came out (actually, it was probably a tape) in 1998 and Harvey Danger's "Flagpole Sitta" and Marcy Playground's "Sex and Candy" were on it.
Anyway. I'm old. And this video proves it -- these young kids are just amazed and bewildered by the very first iPod, which came out in 2001.
