I do feel itās a story about Maeda. From what I know, Maeda actually wanted to be a musician, not storywriter like what heās famous about now. I remembered reading something like āhe wanted to pursue his career on music but he couldnāt so he changed his job direction to writing scenario.ā
I also read (iirc in Hibiki no Mahou afterwords) that he havenāt played game or watched anime much lately, and even he havenāt been buying CDs (even though in the previous volumes afterwords it was shown that he bought a mountain of music CDs on monthly basis). So when the second verse started, it immediately hit me, āWow, Maeda is in a deep sh*t.ā
As for the yellow color, I believe itās a symbol of happiness. Actually thereās a lot of meaning of āyellowā but I think the most common one is happiness.
The guitar is always in yellow, which I believe it was the only source of happiness he had.
The color yellow also appeared in the medicine/drug, and we - as the lyricist as well - donāt know whatās actually in them. Thereās a lot of medication too, so Iām sure he had been depressed as hell, and probably the yellow one is simply a drug to raise his serotonin level - or at least thatās what he thought.
Then we have a stage highlighted in yellow, and he failed to grasp that ray of yellow light.
And in the last part, the yellow butterfly is simply a symbolism for our protag. He finally got out, and heāsā¦ well, happy, I guess?
Now, for Maedaās beliefs. Iāve always thought heās an agnostic atheist. The way he wrote his lyrics and story just told me so.
Like, in BOYS BE SMILE lyrics:
Not everyone can be happy
The gods just roll their dice and laugh
In Kakeru (KSLA-0019 Love Song - this song serves as Sayaās leitmotif sample)
For gods, giving salvation to anyone
Is just like switching on and off the starlights into white, red, black.
Theyāre just merrily laughing.
Also, quote from Little Busters! anime
āThereās no God here. All weāve got in this world is us.ā
The way I see it, there seems to be a bitter tone around gods, and in AngelBeats! he even made the character strike against god.
The lyrics in this song, too, felt like he is discontent with how reality is harsh, how we canāt choose our talent - just like how the people in SSS canāt choose their fate and ended up in afterlife.
Though in AB! thereās reincarnation, and a lot of magical things also reoccurs in Maedaās works, soā¦ yep, I have no clear guess.
Sorry I ended up writing more than I intended.
