How to Follow Set Times and Last-Minute Changes
Because exact set times for the 2025 iHeartRadio Music Festival are often updated up to 48 hours before each night, treat early published times as provisional. To stay current, rely on the festival’s official iHeartRadio app, which pushes real-time notifications, stage maps, and artist swaps.
