All my library was organized and each songs was rated. It tooks me about 18 months achieve this.

Today, I open my Music app, and ALL MY FILES ARE GONE, it's totally empty. Except for four songs I bought on iTunes few years ago.

I've try to reconnect my library choosing the Music Library.musiclibrary file, it didn't works, I've try to find the XML file as the iTunes times, but I found just a very old one that use when I change my macbook pro last year. With that file, it works, but I still lost 12 months of works...

Someone please help me, I can't find the solutions and it's for my work... I've never experienced that before... I'm crying!!

Please help me! 🙏🙏🙏🙏🙏
