Family Share...I have 1000 purchased songs. I can share them all?

[Kendo]

I have 1000 legit purchased songs from iTunes. Not that it matters but I didn't pay for them, they were all through promo codes.

Can I share all of these legacy songs with my wife? Or does Family Share only count for songs and apps purchased AFTER you create the Family account?

After you create the family account, your members can see your "purchchases" on your name. There are all songs inside...
