Another bizarre Spotify #wontfix is how you have (or at least had, this was two years ago) no recourse against someone with access to your account. e.g. Changing your password doesn't invalidate other sessions.

My friend had her password guessed (you can buy hundreds of hacked premium Spotify accounts online for <$1/each) and was powerless against the person who had been using her account. She had to basically listen to what they were listening to, it was a bit comical.

We emailed Spotify about this as it was happening and there was no way to lock this person out. Sorry! They advised her to create a new account and they would gift it with some duration of premium access.

To make things worse, she was the one who started our family-plan, and their customer support was unable to simply migrate the plan to her new account. She registered a new account and added it to the plan. This intruder was basically able to free-ride on our plan and force her our of her own account.

When I later saw the price of hacked Spotify accounts, I thought it was a great value!
