My Question or Issue

For various reasons I lost my old spotify account (my phone was broken) I downloaded the application again but I lost my old data and i dont remember them.. (If I look for my old playlists or my account they seem to have disappeared) But in my phone, "file management" all the files of the songs I had saved on the sd card remained. Their format does not allow me to reproduce them, so I wanted to ask if I could somehow recover my old playlists thanks to these files? or anyway I would like to retrieve my playlists in some way
