Can Artists change the tracks on their profile page?
Yes. Artists have the ability to upload up to 10 tracks. However, to be eligible for a Showcase, your 3 “active” tracks must each have received at least 30 reviews. Once in an active Showcase you cannot change their 3 tracks until they come out of that Showcase. If you decide to deactivate a track and then reactivate it again at a later date, the reviews which the track has previously received will still remain valid.
