Spotify deleted my Ipod playlist!!!!!

[adaly07]

I tried to sync my Ipod with a playlist, i did everything it said about backing up files however when i went to the folder to look ALL my songs were gone, I was so happy to be able to use spotify and get my itunes songs because i havent been able to log into itunes for a long time, But when i went to look at the music inthe folder it was all my stepdaughters music from her ipod which she lost about 2 years ago,,,,,and its nothing but selena gomez and hannah montanna,,,,,,all my songs are gone and im so devestated now
