I guess that there have been a few changes over the years. You can see the way it looked back then more-or-less on the wayback machine. Apparently, my tastes have not changed greatly.
But, that is not the case. There have been so many artists that I've found on Last.fm that have become a permanent part of my listening since then. It was actually here where I first heard Tegan and Sara, and they have taken over my charts. (And did so, even way back when.)

That was when there was a free radio period (I forget if it was a number of plays, or a period of time). When that expired I left for a while, then came back for the scrobbling. I rather enjoyed the recommendations I'd get from Last.fm.
And I've stuck around since then. It's been a blast. …
