I've gone back to having each playlist in an individual player due to numerous complaints that the playlists "skip" when starting. As noted in the last message, if you experience that problem, you can often (although apparently not always) fix it by refreshing the page.
This didn't seem to be a problem until I went to the consolidated playlist player. Thus, my return to the individual players. The downside is that they take up more real estate on the navigation bar on the right. But, I'd rather have working players than more space.
So, now hopefully, you can enjoy them all!
