iTunes is one of the most popular digital players in the market. Thanks to its built-in feature on iPhones and iPads and available app for Mac and Windows computers, it is also one of the most readily available digital players out there, so it does makes sense for many DJs and producers to use iTunes to play tracks and mixes.
There is one major drawback though: iTunes does not support playing certain audio formats. For one, it does not support playback for tracks created using DJ software such as Rekordbox and Traktor.
Normally the solution for this has been to simply use another player to play Rekordbox and Traktor tracks. But now DJs have another solution: make such tracks iTunes-compatible using the DJ Conversion Utility.
