I'm not sure how to solve it. Your playlists are stored locally on your phone, and different OSs and browsers handle that storage different. I don't actually store any of your stuff on servers. I'm probably going to change that, so that your playlists are synced across all your devices.

Thanks for your answer. Sometimes I see the playlists and an hour later they don't. Very strange.
One has to be a special kind of retarded to be a web dev. I like the web, because it's as open as you can get, and the app stores can't de-platform your app because you add a feature they don't like, but man, it's a pain dealing with all the browser inconsistencies. In my dream world, the browsers would open up a sandbox on the person's file system for saving files locally, not just in the browser's database.
I follow your dream!
