Yup, they did this for me back in 2015, and it was a really good customer support experience. I'd actually created a second account & asked them to close my original Facebook-linked one, but they offered to move across all my playlist data etc over to the new account so I didn't have to start over. And they checked in with me to make sure the data all looked good before deleting the other account. I was really happy with how they handled it.
