Good at what it does but doesnt sync across IOS

Very useful at keeping your music together and collecting tabs from across the internet. The one frustrating thing is trying to remember on which iOS device Ive put a particular song....on iPod? No....on iPhone? No, but darn I know I have that song... Ah there it is in the iPad version...
My advice is to only keep this app on only one device if you are like me and have the habit of putting stuff on different iOS devices and expect it to always be available.
If the author provides this one feature, then it would be a definite five stars for me.
