I don't think it does. I've asked numerous tesla people and none seem to know if it does (they havnt had a chance to test it yet)
The release notes are very badly worded and can be interpreted in different ways, and the media certainly reported it wrong. (Although if they were given info like the release notes I understand why)
Spotify keeps a record of what you have played, which is kind of like a play list, other than you cannot delete the songs you didn't like.
Still a way better option than rdio, and tesla have done the right thing by giving us an alternative when realistically they could have done nothing.
Think I'm going to do the 30 day spotify trial, which I guess is why spotify gave us all free accounts.
