Users might prefer to know when the track is available in a certain store rather than any store. Also when the track first appears in some source, it is difficult to know when it is available in the source you would be interested in (e.g. track first appears in Spotify, but only later comes to Beatport or Bandcamp -> user needs to poll the cart to see when the track is available for purchase).
