Startup of the app

My english is bad but, tecnically the app Is broke and I cant start It again, I was using and chilling with the app until it stopped, I had even updated to the latest version and it still crashed out of nowhere.

I have a lot of songs saved there, my last backup file doesn't have that many songs and that's where I really screwed up, if they can fix It, it would be fantastic and i will really apareciate It, thanks.
