There is already several scripts to change the character casing. Except for lyrics searching, what is the issue?Ludovic Michel Crenn commented
the application forces the presentation of its source without any possible parameterization and refuses to recognize tracks with titles or names of artists with eroned names but a simple variation in capital letters is considered as erroned, problematic to then fill in missing information ...
Also, recognize the "&" as "And" or "and" could be interesting
scripts aren't tools for everyone
