Last weekend, my brother came home with a mission. He is a sailor, an officer on a massive oil tanker, and his job takes him on long voyages where expensive satellite internet makes Spotify a distant luxury. He relies on his trusty 120GB iPod Classic for his music library.
However, since his old Apple account was no longer accessible, many of his original purchases were silences in his library. We found his music on my old backup drives, but during the hasty transfer into his "Automatically Add to Music" folder, we created a digital mess. Hundreds of duplicates appeared overnight.
It is a common frustration that neither the old iTunes nor its newer version, Apple Music, offers an intuitive way to deal with hundreds of duplicate tracks. In the past, cleaning this up meant hours of manual work, song by song. It is a tedious, soul-crushing task that most people simply avoid.
Instead of wasting time on manual labor, we decided to solve it with code. What started as a simple CLI script a few days ago has now evolved into a fully functional, commercial grade macOS application: Duplicate Music Finder.
Built with SwiftUI, the tool identifies duplicates by looking at metadata, bitrates, and duration, ensuring that only the best version is kept and the rest are safely managed without messing up the library database.
My brother is heading back to sea now, his iPod restored and organized.
At our company, we love solving real world problems with digital solutions. If you have a task that feels repetitive or a tool you need built from scratch, whether it is a small script or a premium desktop app, we are open for new projects. Let us build something that makes your life easier.
