(edit)
A files field returns an “Error. Files not uploaded” when uploading .mp3, not when uploading .wav or anything else.
This is localhost.
What can cause this?
Could you post your files field blueprint definition, and if you have assigned an upload template, that as well, please?
Is there any more information about the error in your browser console?
And what about file size of the files you’ve been trying to upload?
I ran many differently sized mp3 files through it, and it seems to be a size related error. Although files of only 9MB are returning an error.
This is then more than probably PHP config related.
Thank you.
The default is 2mb PHP limit i think. This can be increased in PHP ini or sometimes through your hosts control panel.

Funnily enough, although increasing the ul size fixes it, the error displayed with mp3 files was not about exceeding file size, as it was for other types of files, but simply “Error. Files not uploaded”. 
This less specific error seems to be thrown in Api.php#747ff.
if (empty($files) === true) {
$postMaxSize = Str::toBytes(ini_get('post_max_size'));
$uploadMaxFileSize = Str::toBytes(ini_get('upload_max_filesize'));
if ($postMaxSize < $uploadMaxFileSize) {
throw new Exception(t('upload.error.iniPostSize'));
} else {
throw new Exception(t('upload.error.noFiles'));
}
}

I guess setting mime types might help. MP3 files are not a common one people upload, so might have been missed out by the defaults of your webhost.
I normally put this in .htacess which covers most file types.
