Ipod Recovery

[ayu'ssong]

My ipod mini got cleared somehow and it doesn't make sense, i added a song and unplugged it and everything was gone, but I guess it can't be reversed now. I searched if there was a way to recover at least my last songlist (the list of all the songs that were on the ipod), and I found this drive recovery program and ran it, and something called itunes.db showed up, and i think i might contain some songlist related data. Anybody who has any suggestions or knows a simpler way, what caused the clearing in the first place, or if this is a common problem, please help.
