"Arrange photos chronologically from birth to present day. Highlight key milestones like first steps, graduation, and recent adventures in cities like Austin or Miami. Play 'My Wish' by Rascal Flatts for a heartwarming touch."
"Start with upbeat tracks like 'Party in the U.S.A.' by Miley Cyrus for early photos, transition to 'Good Days' by SZA for teen years, and finish with a celebratory anthem like '22' by Taylor Swift for the grand finale."
"Focus on 3-4 distinct 'chapters': childhood shenanigans, awkward teen phase, high school triumphs, and current adulting. Keep each section punchy, around 30-45 seconds, with a total duration of 2-3 minutes. Great for a quick toast at a lively bar in Nashville."
