Changing ROMs - Backing Up Google Music Files?

[BJNK]

If I am switching ROMs, is there any way to backup and then restore my Google Play Music files?

I have nearly 40GB of playlists etc and would really prefer not to have to redownload them each time. Is there a way to backup a specific folder and then restore it after flashing the new ROM?

I understand they are DRM protected. I don't want to add them to my computer or anything, I just want to avoid the headahce of trying to DL 40gb of data on a very slow connection.

Hi,

I'd like to also step in and ask for a solution. I myself have 30GB that needs downloading everytime i install a new ROM.
I have tried to use Titanium to tell the system that some kind of ID stays the same, but apparently the music is deleted from the phone as soon as the phone is started for the first time, so I can't really tell whether this would work or not.

Any suggestions would be highly appreciated
