Is there a limit to the number of times you can listen to a playlist (created by somebody else) on Spotify free?

No.

No there is not at lest not what I have found. I have also now been on Spotify Premium nearly 6 weeks now and seem to be liking the service.
It has most of the songs and artists that I want.
Just one or two artists don't seem to list some of there songs on Spotify but nearly all do.
