Spotify – Merge two Accounts
I figured out that i had one Spotify account on my MacBook Pro and another different one on my iPhone.
I wanted to combine my music / playlists and everything else to just one account.
Use the contact site to get in a live chat with a Spotify employee. Tell him that you want to merge two accounts with the username / email of both accounts.
He will ask for the birth date as a validation and which account you want to use of them (the other one is merged and deleted). After 2 minutes everything is done.
