Individual Plan: A Prime member can pay either $7.99 a month or $79 per year to gain access to Amazon Music Unlimited. This enables access on all your devices, including web browsers and smartphones. You'd have to pay $9.99 per month if you're not a Prime Member. Family Plan: Amazon also sells a family plan for $14.99 a month or $149 per year.

For just $14.99 a month, you can sign your family (up to six members) up for Amazon Music Unlimited’s Family Plan that will let your whole crew stream music on up to six different devices at the same time. Seeing as the regular subscription comes in at $7.99 a month for individual Prime members, this group package can save you money each month.

The Individual plan would not allow you to move between accounts or profile. It will stay locked to the account and profile that signed up for it. The best option would be the Amazon Music Unlimited Family Plan. This way you can have separate profiles and playlists, but only pay once.
