"good to know" is a short album, timing in just 34 minutes for the complete physical album. Within that time, she explores a very wide variety of themes and shows her and her producer's high ability to translate abstract thoughts into tangibly impactful notes.
Certain album tracks are continuously linked, which reminds me of Beethoven's Piano Concerto 5 and its second movement is linked with the third; then the Romantics like Mendelssohn took that a step further in his piano concertos.
The first three tracks markedly show the dark vices that had consumed her in the past. Bad Habits, So Bad, Pedialyte, and Comeback are tracks in that vein. As such, these tracks have explicit thoughts/lyrics.
Other tracks are far more reflective in nature. These tracks would be Small Things and Think About You.
Certain tracks are about relationships. These would be Man, Lonely Hearts, and Don't Talk Me Down.
Gold is the track I cannot quite comprehend yet.
The final track brings forth a feeling of personal touch and warmth not dissimilar to the finale of the Eroica Symphony by Beethoven. Seem like trend when people write homages for someone they respect/revere.
Being the fifth album release of her career, good to know marks another point of development in the battle-scarred career of JoJo's career.
My favorites are Lonely Hearts, Small Things, Proud(outro), and Pedialyte.
