1. NBS shows total number of station creates, and AMP shows station creates - deleted stations, so it’s expected that they’re showing different numbers.
  2. Within Pandora, a single artist may have multiple versions, such as “Taylor Swift” and “Taylor Swift (Holiday)”, which help with playlisting. In AMP, you will only ever see data for one at a time, however within NBS, the values will be aggregated across each version whenever looking at artist-level metrics.
