Comment (by scotterickson):

 This issue began happening in January 2017 and had never occurred before
 that. I can't guarantee which version of WP was running when it started to
 occur. However, the remedy suggested on this ticket (using disable mime
 check plugin) did resolve the problem. I know that is no guarantee that
 this is the same bug (the remedy may just have happened to resolve the
 issue), but am tracking this ticket and will see when 4.7.3 comes out
 (assuming that is when this is resolved) whether that resolves the problem
 without the disable mime check plugin (as I would prefer not to use that
 workaround any longer than required).

 Replying to [comment:91 programmin]:
 > @scotterickson Did the mp3 uploading problem happen for that file on
 older versions of Wordpress? If so that is likely bug #32318 where a
 seemingly working mp3 file has some header info that WP does not like,
 leaving the upload uploaded but never added to Wordpress media library.

 > I have seen that on several occasions and I agree it's annoying, but
 that may not be related to this 4.7.1 update, that bug has been happening
 for at least since WP 4.3.
