I need to host some mp3 files for a closed paid membership, but we really dont wanna host them on the site as they'll probably hawk quite a bit of bandwidth. We have a pro account for video at Vimeo which works superb, but they don't wanna host audio at all.
So, where would you put it? Paid is fine.
Have you looked at http://soundcloud.com/
You can host private files if you want to http://soundcloud.com/101/private-sharing
That looks great! Will have someone look at it :) Cheers!
