send iTunes music to a friend?

Bruce,

Invite them over and press "Play." Or sync the list to your iPhone and go to their place and play it.

Yes, seriously. The options that used to exist for posting what was called an iMix, or for gifting an entire playlist at once, are no longer available.

You can purchase each song as a gift to be sent to your friend.

It is not legal to give a copy of your music to anyone. You would have to buy the gift for your friend.
