Believe me I tried, it doesn't work in my specific case because the account was initialised via Facebook. They gotta make a new account and copy over my old data. That works, and the Spotify helpdesk is excellent.

Problem is, I use Premium via a voucher from my ISP. My ISP no longer gives these vouchers, and its claimed. So for a new account, I cannot get Premium for "free".

I should feel lucky my ISP hasn't disabled the existing vouchers (the main branch of the ISP did).

I deleted all of my Facebook data about a year ago and I actually had to create a new Spotify account to disconnect it from Facebook. Glad to hear they are improving this process.
