^Same here! I like the perseverance theme on it.
There are many Ayu songs that I got encouragement:
*Beautiful Fighters
Lyric wise, its all about never give up your desires to fight the hardest day of your life.
*MY ALL
The title fits for this song.
The lyrics reminds me of I wasn't alone because there's God who was encouraging me through times of famine and discouragement.
*Bold&Delicious
Its the same as Startin' but with unusual musicality.
YAYAYAYA GAGAGAGA DADADADA WOWOWOWO anyone? :irk

Those 3 on my list are the one who catches my current condition.
