I am not a RekordBox user, but as fas as I know, you have to export your files with RekordBox to the USB-Stick, and Rekordbox writes additional info (Beatgrid, Cuepoints, etc.) as well to the USB as an additional file.
Usually the DJ Software saves Beatgrids and cue points in a proprietary databases. (thats at least true for Traktor, RekordBox, Mixvibes, VirtualDj) (I think Serato saves them also in tags, but the tags are named with Serato as name prefix)
So they don’t overwrite each other, so nothing to fear.
And on a side note there is a Software coming, which can sync those stuff like Beatgrids and Cuepoints between different DJ-Software, its called Rekordbuddy 2.0.
Here an interesting interview on the topic:
I think this whole idea of sharing music is a great idea. And even better with this additional twist.
To get more people involved this should be announced on the Front page of DDJT.
Because selecting and sharing music is the essential thing of being a DJ, all that controller and technical stuff is only a means to an end: playing great music.
