maybe tasting represents achieving the song's full potential, if you were doubting yourself at the time.
the whole point of that song, from the start, is the title. i was envious of other songs (probably country songs) which have a title which already has some cleverness baked right in. so i thought of one, "the moon is made of cheese (but i can't taste it)". so just went from there and tried to continue the game. you can't taste it, but you like the way the texture feels when you lick the surface. Makes perfect sense, but is also completely ridiculous. so the next line "the rumors start to go round the world that i'm crazy" well of course, because you're licking the moon. but no, instead, it's "becaususe you can't taste the cheese". so the fun score, for me, continues to be upheld up to that point. Next stanza, start with a line to echo the same theme as the first. famous phrase ('the grass is always green') then change it ('but i just changed it'). From this point, the key changes start to play an even more significant role, but, the game remains the same. i'm simply in search of quality songwriting
