Recommended Songs feature on playlists - is there a song limit?

[discohijack]

Howdy.

I have a playlist in which I catalogue all the good songs I've heard using Spotify, and one of my favourite functions was the Recommended Songs feature at the bottom - it helped me to discover a lot of enjoyable albums.

But I've noticed that, since hitting the 1.5k milestone, the feature has disappeared. Is this a glitch, or is 1500 songs just too much for the Spotify software to analyse? Thanks everyone.

(I'm using Windows desktop btw, if that means anything.)
