Last post of the night for me, I'm way too addicted to Hubski. Yes, there is a limit. The maximum it should be is two hours due to the fact that this is meant to be a view into another person's taste in music, not their entire library. I will personally keep my playlists around an hour long. Another backing reason for this is that most free file hosting services have a limit, and we don't want that to be a hindrance to our swaps.
