I have all mp3 stored in che micro SD card.
Each time I remove the card I lost the favourite playlist.
There is a way to backup the favourite playlist?
Where are stored other user playlists?
p.s. I think that storing "favourite" flag onto ID3 Mp3 tag data will be really useful...
Playlists can be backed up with Media Go.

There is another way without use Media Go?
