TuneRanger connects iTunes-running computers over a network, allowing music, video, and playlists to be merged from one iTunes library to another seamlessly. TuneRanger even works across platforms letting iTunes on Windows communicate and synchronize with iTunes on Mac or any combination. TuneRanger offers true synchronization. It compares songs and videos on all computers and only moves what has changed. It even does this for playlists.
Power users will appreciate TuneRanger's more advanced sync settings and filters and its capability to perform bi-directional iPod synchronization - including iPod to iTunes transfers.
TuneRanger incorporates numerous tools designed to keep iTunes and iPods clean and optimized. These tools include: an automated duplicate manager, an orphan file remover, tools to remove unlicensed songs, add or remove disconnected files, and a software to copy album art from the iTunes database to the actual music files making the album art portable and accessible to other music managers and players.
