From 2013 Debut to Timeless Classic: the 'Best Day of My Life' Journey
By Robert Thorne
Q1: What inspired American Authors to write "Best Day of My Life"?
A1: Frontman Zac Barnett and guitarist James Adam Shelley wrote the track while living together in Brooklyn, New York. Struggling with empty bank accounts, odd service jobs, and music industry rejections, they chose to write an upbeat song visualizing a day where everything turned around, using escapist songwriting as a release from daily pressure.
Q2: What key is "Best Day of My Life" in, and what are the main chords?
A2: The song is written in the key of D major at a tempo of approximately 100 beats per minute. The main chord progression for the verses cycles through D, G, Bm, and G. The chorus relies on D, G, Bm, and A, making it straightforward to adapt for acoustic guitar, piano, or ukulele.
Q3: Which album features the single, and when was it released?
A3: The single is featured on American Authors' debut full-length studio album, Oh What a Life, released on March 3, 2014, through Dirty Canvas and Island Records. The track was originally distributed as a single in early 2013 before gaining widespread global traction.
Q4: Why was the song used in so many commercials and movies?
A4: Island Records proactively targeted commercial brand partnerships and trailer placements when terrestrial pop radio initially overlooked the single. Its punchy banjo intro, driving kick drum, and universally positive lyrics made it ideal soundtrack material for brands like Hyundai and Lowe's, which fueled its mainstream momentum.
