Change the audio file icon (globally-all associated filetypes together) ?

[SEAworthy]

I wonder if there's a way that a custom icon could be used for the audio files- not to differentiate file types, but just for all the audio files that are associated with MusicBee.
 If not, could someone point me to a solution that can get me to that end? I've seen mention of a filetype solution but I can't find it.

Thank you!

Hi, welcome to the forum!  I don't know if it has changed since Windows 7, but there's a link here on how to change Windows file type icons: http://musicbee.wikia.com/wiki/Icons
