Here is a possible fix for you if you encountered this problem when trying to import some of your music files into Ableton.
Finally I had some spare time to mess with some music again, but encountered a problem when using Ableton that I had not experienced before. After trying to import some of my music clips in Mp3 format, the error message “Could not be read. It may be corrupt or not licensed” appeared, even though I had done the same plenty of times before.
I decided to do some digging, and plenty of people seem to have encountered this issue, but with plenty of suggestions of ways to solve it, that did not help me in my case. I then noticed that my mixing software “Traktor” had written some custom tags to my soundfiles if they had been analyzed, after reading a forum post of Traktor causing this for some reason. For some reason Ableton consider these soundfiles corrupt when encountering such custom tags.
If you use Traktor/any other possible music software as well as Ableton and encounter this issue, remove all custom tags from your soundfiles and it should work (unless the file is actually corrupted or DRM’ed 
).
My favourite audioplayer Foobar2000 is able to do this easy, simply right click the soundfile(s) and choose properties, and then select remove tags from the tools button (do this under both Metadata and Properties tabs).
Happy producing
Worked for me by copying the files to a different folder than the one i use traktor to access. Thanks anyway!
I tried that as well but with no luck, as they were still labelled as “corrupted” after they had been analyzed by Traktor.
But it’s a more simple fix, maybe it will work for others
Seems odd, but installing Apple QuickTime (v7) resolved the issue for me without having to modify mp3 files.
Hi guys,
installing Apple QuickTime (v7) helped me too
Thx alot!!!!
Good man, respect !!!
I never reply to these but I know how frustrating these tedious little errors can be. Just wanted to thank everyone for the tip. Quicktime 7 did in fact fix the issue for me.
From reading other forums I had a hunch that there may just be a missing codec or something and some other people recommended 3 separate packs to fix this same issue.
If this is the case, and I believe it to be so, Quicktime has all 3 of these packs included in the download.
QuickTime install worked for me too!
I have tried both fixes, removing tags and installing Quicktime. My MP3s are still “corrupt”. This is a major problem for me, ALL my music files are MP3s and I have a radio broadcast to do. In serious need of a quick fix! Anyone any ideas?
