For our Canadian customers, there are some important changes coming to Slacker accounts being used on Sonos. As of today, the Slacker experience on Sonos for free subscribers will be limited to a certain number of track starts. What is a track start? Each time you begin a new song, it is counted as a track start, regardless if you play the song to completion.
With a free Slacker account on Sonos, Slacker will allow for 200 track starts before you are asked to upgrade your subscription. Once you reach 200 tracks starts, you'll receive an audio message notifying you that “once your track start reaches 600 plays, you will need to transition to a subscription”. After 600 track starts, you won’t be able to play anymore without a subscription. Subscription options include Slacker Radio Plus or Slacker Premium service levels, and you can find more information by visiting http://www.slacker.com.
