With regards my comment about post 1990 music it's quite frightening really. For this quiz I came up with about 50-60 of the songs I used from memory (the songs not the lyrics, obviously I look those up) and then I used Google to check out lists of songs with Boys/Girls names in them to see if I'd missed any obvious ones. I'd say most of the top 100 lists only had around 20-30 of the songs I used, the other 70-80 on their lists were songs from the past 20 years that I'd never heard of (nor had I heard of most of the artists).
