I think the tag below says it all

Since I'd started using last.fm, it's recorded just over 28,000 songs that I've played. I don't know how many hours of music that is, but it's enough to create amusement when I tune in to last.fm's "My Library" online radio station.

The "My Recommendations" station takes what you listen to and gives you things you've never heard before. The "My Library" station, on the other hand, takes only stuff you've played in the past and then plays it again. I bet it would suck as a feature if you've only logged a few dozen songs, but I've given it a bit more to play with.

Now, some time in the last three years, I must've listened to Elton John's "My Father's Gun". I don't know when or why, but I did. And I was logged in to last.fm at the time, and it knows all.

The point here is that I'm just tickled that last.fm's giant computer brain decided that the first two songs I wanted to listen to this morning were Hayseed Dixie's cover of "Rockn' In The Free World" followed by that Elton John song. *pats giant computer brain*
