Why some mp3 gives me FSBTool ERROR when importing

I want to read some mp3 files and convert them to audioclip and I'm getting this error with some files

Errors during import of AudioClip Assets/Audio/Custom/katyperry.mp3: FSBTool ERROR: The format of the source file is invalid, see output for details. FSBTool ERROR: Internal error from FMOD sub-system.

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

I also get the error when I import the audio file manually, I have to use a program like audacity or https://online-audio-converter.com/ to reenconde the mp3 file, but this is not a viable solution for me, because I need to import the file via code. I am using unity 2020.3.33
