讨论 → Randomizer repeating tracks too often

I have been using last.fm for a couple months and mostly listen to my library radio and I have really enjoyed the sound quality and seems like a better tool to suggest new music....but, I have noticed that the same tracks are showing up on a much regular basis than I would expect with a decent sized library. Especially when I first start up last.fm.

I know this post is old but it hasnt improved at all. I have hundreds of artists but it always plays the same tracks too often.
