I'm trying to share some ideas with other musicians I know via email, but I can't get the files small enough. I'm taking my GB idea and dumping it into itunes, then attaching the itunes file to an email. They're too big. The GB files end up in itunes at 1411kbps, which turns a 2 MB song into 60 MB (too big for an attachment). What can I do to change the kbps or is there another route I should take.
