@S-TYPE > There could certainly be malformed data within the ID3 tags that can cause loading problems. I know I've seen more bad MP3s from Beatport thanks to the embedded artwork than any other issue with tags. It could also be bad data in the MP3 itself, which would still allow it to play in many players and software, but cause others to crash. Typically, there's no reason to remove all the data. If the problem comes from linking to rekordbox, chances are it's not a problem with the MP3s but your computer or the hardware you're using to network the player to the computer.
