So after i saw YouTube and my own soundtracks arent working and its just black screen stuck forever i found a way how to use my own music so its working. You just have to download music you want from YouTube to MP3 ( i used yt1ss.pro) then after you download mp3 version of your music, convert it to OGG file ( i used FreeConvert) after that all choose the OGG file song and it's works perfectly :)
