How to attach the song and mail

Just posted same in another thread.
you can't but if you Google File Flyer you can send files up to 5 gig I think it was last time I looked, you don't have to join or pay anything for it, just Google FileFlyer. And follow instructions. Just checked and at first you are limited to 400mb in one go x 3 but after you've sent one file the limit goes up, it uploads your files onto a server and sends an email message with a link for the recipient to go and download the files.
