I rearrange my music so it has all the right titles and artist, and in the rearrange also changed the name and position of each file. When I tried to open Juk again it just kept crashing. I opened it from the console and it started to show that the files where missing and at one point it crashed again. The next time I open Juk via the console I press Ctrl+C when it started to show that the files where missing and it resolved the problem. Juk opened and reload the music again.
The thing is if you don't know how to use the command line, it would kept crashing.
