I think Taka has a slightly UK English way of pronunciating some words in his singing. It might be because English words when written phonetically in katakana (Japanese alphabets for writing non-Japanese words) often have a more UK English-sounding pronunciation. For example the word "are" in We Are is sung as "aah" with the silent "r" and in this song when he sings "exactly who you aah (are) pretending" not with a hard "r" like in American English.
Just wondering if you’ve ever been suggested to try The Warning? You seem to go down rabbit holes. The Warning is possibly rocks biggest rabbit hole that exists!
