Trying to cleanup my music library this morning. It was easier to write this script in Swift than try and figure out the equivalent in Bash.

// Trying to cleanup my music library this morning.
// It was easier to write this script in Swift than
// try and figure out the equivalent in Bash.
//
// I'm using this in conjunction with Beets <https://beets.io/>.
//
// Prior to importing music into my library with Beets, this
// script attempts to callout any problematic album folders that:
//
//    1. Contain BOTH .flac and at least one lossy format
//    2. Contain MULTIPLE lossy formats
