Uploading .mp3 files http error - 2 "exact" files one successful other fails

I have 2 equal .mp3 files - technically different files but both exported from Audacity using the same settings and the same original audio. Exactly the same size, same content (albeit processed separately) - one fails and one succeeds.

Both files play fine but could some character in the file be tripping up the PHP upload?

I see this error - ap_pass_brigade failed - in the log from last week - GoDaddy takes a long time getting the logs saved and today's errors are nowhere. related?

Running PHP 5.4 on GoDaddy

I have tried the 'fixes' for the imagick issue in PHP 4.5 to no avail.

my htaccess:

SecFilterScanPOST Off
/IfModule

GoDaddy's senior tech had no idea what was up - maybe a corrupted Wordpress? I did however do a refresh install and no change.
