mp3 download

[steve-d]

I am having problems with putting downloadable mp3 files on my site. I posted an inquiry a while back and someone told me to add AddType application/octet-stream .mp3 to the htaccess of the directory that the mp3s are in. I did that and on some computers the files are still just opening in a media player, while on others a box comes up asking what to do.
