Have you ever wondered where all those unwanted Last.fm scrobbles go to die? The social networking site’s “Most Unwanted Scrobbles” chart, which lists the top five artists and songs manually deleted from users’ listening histories, may ultimately be just as interesting as users’ official profiles:

Tracks
1. Britney Spears - Piece Of Me
2. Nelly Furtado - Say It Right
3. Britney Spears - Gimme More
4. Amy Winehouse - Rehab
5. Avril Lavigne - Girlfriend

Artists
1. [unknown]
2. The Beatles
3. Radiohead
4. Britney Spears
5. Avril Lavigne

On the artists side of the chart, The Beatles and Radiohead make sense -- users probably delete Kid A tracks en vrac to allow other, less-known artists to top their charts. But Britney Spears and Avril, along with pretty much all of the tracks, are grounds for some serious sociological speculating. There are guilty pleasures -- ones we admit to without compunction because, y’know, they’re funny or ironic -- and then there are tastes we would never admit to, for fear of utterly destroying our social being. Which are these? It makes one wonder what the list would look like if it were expanded.
