mp3 exports


:confused:For the most part I haven't had problems with these but one friend reports he can't open these files after I've send them as email enclosures. I've exported them by using "bounce" and generally do them at 160 rather than the usual 128 for these purposes.

He is running Snow Leopard as well and can only open them if I send the link to them on my website.

I assume that these mp3s are standard but he gets a message saying that he doesn't have the software to open them.

Ideas anyone?
I haven't heard of an email program that's corrupting the mp3s, but if that's the case, then what happens if you zip them up first? Just a thought.
Thanks Pete,

I'm only trying to eliminate the possibility that I've been doing something wrong but I see, after checking my old emails, that the problem predates my use of Logic and "bouncing" and seems to be only with this one user so far.
I have had experience with email stripping the headers from mp3 files. The solution, as Pete suggested, is to zip the files before attaching them.
Someone that user knows came over and they discovered that the problem was he couldn't find it in iTunes. So problem solved for the moment. But I'll certainly check out the zip option.

Thanks both!
