content type for mp3 download response

I have created a simple HTTP server which allows users to download files. But this does not seem to work for mp3 files. The content type currently is "application/misc". In order to make it work with mp3 files , I've tried "application/mp3" , "application/data" and "application/mpeg".

What would be the right content type for mp3 or audio file download, and am I missing some other headers?

EDIT: The file should automatically start downloading rather than prompting the user for saving it somewhere.

Try "Content-Type: audio/mpeg"

Update

To encourage the browser to download the mp3 rather then streaming, do

Content-Disposition: filename="music.mp3"'

.mp3    audio/mpeg3
.mp3    audio/x-mpeg-3
.mp3    video/mpeg
.mp3    video/x-mpeg

Using Content-Disposition: attachment... forces a download box to appear instead of having to right click -> save target as.

After a lot of research, I found some resources (some on SO) that led to this solution. It is the most cross device compatible solution out there and solves a lot of issues especially with Android devices (a lot of issues with them apparently).

Content-Disposition: attachment; filename="my_mp3_filename.MP3"

Take note of the upper-case extension. That is important.

Using Content-Type "application/force-download" worked for me.

try below content type it worked for me.

"audio/mpeg3;audio/x-mpeg-3;video/mpeg;video/x-mpeg;text/xml"
