Hi there!
I have a suggestion for a future Rekordbox iOS update. I use an iPod Touch 5th Generation 64GB and I've noticed how much of my space has been used up with other apps. I'm thinking it would be a good idea for Rekordbox to have a media player mode, where tracks can be listened to from the program and can be played through automatically or shuffled like in Spotify. That way you can use the Rekordbox data to play your tracks without having to add duplicates in the iPod's music player.
Let me know if this is a good step forward.
Thanks!
