Taylor Swift's Eras Tour highlights include a coveted acoustic set.

She alternates between guitar and piano performances on stage.

Fans worldwide eagerly await her song selections via social media.

Swift imposed a unique rule: each song can only be played once, unless there's a mistake.

In a twist, she reset the rule for the 2024 leg.

During her final 2023 show in Sao Paulo, Swift announced the change.

The 2024 tour kicked off in Tokyo with promises of surprises.

Over the year, she plans to visit 23 cities globally.

Fans can track which surprise songs she performs at each stop.
