I noticed that one of the recent firmware updates eliminated the checkbox which allows high resolution audio when using your own paid Slacker account. (The checkbox used to appear next to the sign-in button at the bottom of the Slacker window.) It seems that this high resolution setting is now turned on all the time, which creates a new problem for people using their own Slacker account. If you are in an area that has marginal cell reception (one or two bars / LTE), your personal Slacker account will not be able to load songs fast enough to play them without stopping several times in mid-song. The free Tesla Slacker account on the other hand will play just fine, but it does not allow access to many albums that you can find on a $10/mo Slacker account. A good example is Bob Dylan. The best of his newer albums cannot be found on the Free Tesla Slacker account, but all of his albums can be found on a paid Slacker account.
