The lyrics in the Green Day song, "Basket Case," can connect to Holden Caulfield in several ways.
Billie Jo Armstrong of Green Day said that he wrote the song because he believed that he was suffering from a mental illness: "The only way I could know what the hell was going on was to write a song about it." This can be seen in the opening lyrics: "Do you have the time to listen to me whine / About nothing and everything all at once."
Holden can be connected to this, as he often speaks about "nothing and everything," sometimes, "all at once."
The song asks whether the listener has the time. Holden presumes that the reader does. In both settings, the narrator is going to lead the reader in a voyage through the mind, an exploration that is far from certain in terms of destination and end result.
The chorus of the song is another instance where there can be direct relation to Holden. The chorus wonders about the condition of sanity:
Sometimes I give myself the creeps
Sometimes my mind plays tricks on me
It all keeps adding up
I think I'm cracking up
Am I just paranoid?
Holden can be related to this chorus. Holden's own unreliability, his questioning about his identity and about whether or not he is insane are all instances where he can be related to the lyrics.
There is a self-questioning about his place in the world, one filled, in his view, with "phonies." Consequently, as expressed in the song, Holden is uncertain about his own condition and place in the world, like the words of the chorus of "Basket Case" suggest.
