Visit UMG’s website to RSVP for a Listening Party on August 5th at 5PM PT / 8PM ET. It appears that you can sign up for *NSYNC’s mailing list, then it gives you additional information on how to log in.
This event will require a Spotify account. It appears that you will be able to “sync” your Spotify to listen with the others.
The “fine print” from *NSYNC’s website: * To join the party, all you need is a Spotify free or premium account. For the best playback experience, please ensure the Spotify application is downloaded onto your device, use the ‘Sync’ arrow buttons to synchronise with everyone else. If you do not have a Spotify Premium account, you can still join the experience, but please note that playback may not be synchronised with everyone else.
