I had this same issue using my Amazon Music desktop app on the Mac. Ultimately my goal was to try to get my Amazon Echo devices to respond to commands for playing select songs in my library, for which I found two solutions and one of them was to pay for their cloud service. To get my iTunes library into their cloud, I figured I had to use the Amazon Music setting "Automatically import music from iTunes." I'm not sure if that's really the case, but I wonder if that's where the "corruption" really is.
At any rate, after that I did a bulk upload and let it run for a while. But many songs then got marked with an exclamation point and stated the upload failed. When I retry each one, it says it cannot upload due to corruption, which seems wrong. The file plays okay. It's an MP3. Nothing appears to be wrong with it.
So my workaround is this: In the Amazon Music app, in My Music > Songs, I right-click on the offending song and select Show on Computer. When the finder reveals the real file, I drag-and-drop the file directly into the "Upload: Drag & drop here" action on the right side of the My Music window. Then it seems to work. It's time consuming though, so maybe there is a better / faster answer.
