Bypass mime type lookup from content for .flac files

This seems good to me -- it seems very unlikely that a ".flac" file would not contain flac data (it's such an uncommon format as it is!)

I am afraid all media types can have an ID3 header. How about falling back to the "file type by extention" approach for to all ID3 header files?

That should be a safer route, that is easy to tweak in case.

A full solution would be to lookup the mime type behind the ID3 header.

We may also limit the extention based approach to soundsources known to be able to skip an ID3 header.

This is not a request on this PR, I am just asking for your opinions.

Let's defer extended workarounds until bug reports arrive, step by step. I consider everything else over-engineering at this point.
