"Sorry, there is no more content available for this station."

I'm getting so tired of seeing this error message in the Last.fm client. I think the problem is tightly related to the problems described here, here and here. Right now I'm trying to listen to scenemusic's Library, which should contain 2.624 artists. That should mean at least 20.000 songs, perhaps even much more. Still, Scenemusic's library station doesn't have enough content and sometimes even stops playing right in the middle of a song.

This is not a configuration issue on my part. I'm not alone in having these problems. I'm highly confident it's related to all the other problems with seeing only one song per artist, bad randomization, etc., and it's something Last.fm's engineers needs to have a look at and fix.
