Amazing Blir! Being relatively new to this board I didn't know about your work on this...amazing![8D]
I don't know if you are aware of much happening here in OZ but there is a national 'youth' (but many more of us are regular listeners) radio station which broadcasts to the whole country (as part of the ABC) called Radio JJJ.(or TripleJ as they call themselves now).
This station has been running a 'top 100' every year since 1989, and guess what! LWTUA was number one for the first two years and second in the third (1991) when bloody Nirvana pipped it into second spot!
Check out the full history of the polls here.

"triple j's hottest 100 is one of the largest public music polls in the world with millions of individual votes counted since it's inception in 1989."
After this they changed it from fave all time song to only songs released in that particular year, so the nature of the list changed.
Cheers.
