I bought air pods and connected them to my apple id, why don't you offer me 6 months of free apple music?

If you have never signed up for Apple Music before, and never used a promotion before, contact Apple Support for assistance. Use the link at the bottom left of every page of these forums.

Perhaps you have already used Apple Music with your Apple ID?
