Haven't gone through the whole list, but I'd estimate probably 2/3 to 3/4 of the 100 I have. I know I have all of the top 20
@koputai - "the list really reflects the station's demographic" True, it's a survey by a radio station. But the interesting thing, I thought, is that it's a youth radio station and still so many older songs made it. I reckon the target demographic of JJJ is teens and early twenties maybe. They wouldn't have been born, or at least not listening to the songs as they came out and were hits at the time, but obviously do listen to them now.
@toryglen - you'll never be an Aussie with that music taste
Not so much on songs you like, but the JBT comment
