Lack of Data - Aramis Estevez vs. Deathwatch Beetle Repairman?

I have scrobbled the Big River soundtrack to last.fm, which means that Aramis Estevez is one of the artists that I have scrobbled. I wanted to listen to Estevez some more, so I began playing Estevez's station on last.fm - and was greeted with a song by Those Damn Twins.

And then was greeted with a song by Deathwatch Beetle Repairman.

This seemed odd, until I realized that I was one of the few people on last.fm who has actually scrobbled songs by Aramis Estevez - and that therefore last.fm had concluded that all of the artists on my playlist were similar to Estevez.

I confirmed this by looking at Estevez's similar artists page.

As of this evening, the third artist listed - one with a "super similarity" to Estevez - is P.D.Q. Bach.

"Very high similarity" artists include Helen Sventitsky, Ontario Emperor, and Mocksession.com.

However, once last.fm gets more data on the artist, these types of things will be straightened out.

For example, a couple of years ago, last.fm thought that Sventitsky and Ontario Emperor were similar - primarily because both artists were listened to by FriendFeeders.

But now that a couple of years have passed, last.fm has figured out that Helen sounds nothing like me. And with this additional data, people who like Helen's music aren't being subjected to synthetic instrumentals.
