:thought_balloon: I imagine that a small source code refactoring would be helpful. * How do think about to [reduce the scope for the variable](https://refactoring.com/catalog/reduceScopeOfVariable.html "Reducing the scope of a variable") which [is used for an index in a loop of the function “cd_delete”](https://github.com/lipnitsk/libcue/blob/7176a1faccecbfe2d4cca2f776177439ca49cad2/cd.c#L83 "Update candidate")? * Would it be more appropriate to use an other data type than “`int`”?
