I can't download my beats to Apple / iphone / ipad, can you send to my email as an attachment?

Sorry you're having this issue, it is a known Apple problem...

The downloads are too big to be attached to email so they have to be download links.. they will work from a computer.  Unfortunately many Apple devices don't download the files the way most other devices do .. see this YouTube video for more information (lots of people have the same problem from looking at the comments) - https://www.youtube.com/watch?v=s-axYh1WV_o

Sometimes the file will go to your iTunes account as well, so you can try looking in there.
