It would be good to NOT to show the sweepers / station id's as these usually have the wrong album cover art associated with the track and it looks tacky. If we could send empty metadata when any of these tracks play it would give the stream a bit of polish for those who show cover art and now playing data on their websites and mobile apps.
I second this feature request. I'd appreciate the empty metadata option for station ID's too.
Most of our customers who have had this issue put all of the station ID's / sweepers into a single artist name, such as "Monster FM" for the artist, which queues their cover art provider (such as GetMarci for example) to show the station's logo in place of the cover art. If such a feature was implemented to show empty meta data for these types of tracks, it would have to be optional.
