I have bought the full version of TuneXplorer for write down the key of songs for mixing.
But I Can’t import that in Mairlist.
How can I do this?
Do you use mp3 files?
Would you please write the license (serial) number of yout mAirList in the forum profile?
The code you have written there can’t be checked in order to list you as a verified customer. Thank you. 
Hello
I use mp3 files and add it to my account
Okay, that’s the solution. mAirList does not import each attribute out of the ID3 Tag. This has to do with technical restrictions. I have to look for the precise reason in the forum.
In codecs like AAC or FLAC there is no restriction, the “value couples” will be imported as “other attributes”. So it has to do with mp3 / ID3 Tag, where each attribute must be programmed individually.
