In 2019, Beatport will begin an "annual cleanup" that removes any track in their store that has not sold more than 1 copy since it's original release date.
The cleanup will happen late in the year, each year, but will only cleanup content released before January of that year.
For example, the 2019 cleanup will happen late in 2019, and will only remove tracks released before January 2019 that never had a sale.
The cleanup is only happening on Beatport, so tracks will *not* be removed from other platforms. However, TraxSource has a similar cleanup every 2 years.
