I didn't think Mitch ever meant triple J, i was just being a smart ass. However i would say JJJ has gotten a fair bit mainstream recently. But obviously no where near the extent of what ever the other channels are.
Back on topic i still think its impossible to name what you think are the top 10 songs of all time. Maybe top 10 songs that shaped you when growing up or shaped your music tasted or something along those lines
I mean ill look at my music library and trying to compare some stuff to others is like apples and oranges. Even things within the same genre are hard to judge into a top 10 type way.
