For those of us who have multiple Apple IDs (e.g. one for the store and an iCloud), what are people planning on doing for Apple Music? This is a well documented problem - a lot of long time users were required to sign up for a new Mac.com or Me.com ID separate from iTunes and thus music and apps got tied to one and iCloud email addys and data to another. Apple has never released a merge option. No big deal, since you can use Apple Store with one ID and iCloud with another... until... Apple Music. Now if I want to do a family plan, and I invite my family members, do I invite their iCloud ID or their Apple Store ID (which has their music)? This seems like the ID situation could get complicated again. Any thoughts?
