To get Spotify presale tickets, you need to be recognized as one of the top fans of an artist based on your listening habits on Spotify. Spotify selects these top fans using their data and sends them "Fans First" emails containing unique presale codes or links to access tickets before the general public. To increase your chances:

• Follow your favorite artists on Spotify.
• Listen frequently to their music to rank among their top fans.
• Make sure you are opted in to receive Spotify emails and notifications, including push notifications and email alerts.
• Keep an eye on your email around the time presale tickets go on sale, as codes are typically sent shortly before the sale starts.

Spotify does not handle ticket purchases directly, so the presale email will include a link to the ticket vendor's site for buying tickets. In summary, being an active listener and follower of an artist on Spotify, with notifications enabled, is the key to getting Spotify presale codes and early access to tickets.
