this song is about a guy dealing with his homosexuality.
IM BLUE
apple tree apple pie
if i was green i would die
i would beat up a guy
i will bleed i will die
in Aberdeen, i would die
i believe im bi
im in need of a guy
Let us do a line by line analysis. 1st 3 lines is his denial of being gay. he wants to beat up people like him because he cant accept that image, like the "apple"'s tree.
Next, he wants to curse himself, in aberdeen he will die. (self hatred)... before accepting himself in the last two lines.
