The idea is cute. But I know what years I went to elementary school, high school, and so forth. And it links to fewer songs than the Billboard website.
The other problem is that it doesn't ask what kind of music I listened to when I was growing up. I went to a Fundamentalist Christian high school. So the groups I listened to -- Petra, Stryper, Michael W Smith, Daniel Amos -- wouldn't be in your musical memory lane.
Good luck making a "musical memory lane" of nostalgia.
