When will Rekordbox support m4a ?

Rekordbox 6.6.9 still have issues playing m4a files.

Its a shame - its the format of 2$ iTunes tracks

On some files, the sound level comes up and down - its just inaudible. 

Would ever Pionerr rekognize this problem and resolves this bloking issue for using Apple iTunes?

An other simple solution is moving to Serato DJ.
