Why won't my song/audio upload?

if you are trying to upload audio from your android phone or tablet, we sometimes run into issues with android architecture

The android architecture handles the file type extension differently that other operating systems, which can cause problems.

E.g. On windows PC, Mac and iPhone - an audio track is usually given an extension like ".wav" or ".mp3". Resulting in a file that looks a little like this "Your_song.mp3"

However Android will often leave out the extension completely, so it is simply named "Your_song"

Even though your android phone or tablet will recognise it as a song, most other operating systems will not know the file type without the appropriate extension.

To our upload engine it appears like you are trying to upload a file of an unknown type...  It can't be sure if its a text document, a ".exe" file, a virus

If you add the correct extension, e.g. ".mp3" to the end of the file name... this usually resolved the issue.
