Thanks for the feedback! Regarding the tilde placement — I placed the tilde at the end of the first line intentionally, because the vocal sounded more like a broken-up vowel repetition (“kn-o-o-w”) rather than a smooth syllable carryover. It can be heard more clearly when played in slower playback. It wasn’t meant to indicate a prolonged sound, but rather that kind of staggered delivery.
Tildes should not appear in the same syllable after the vowel, but instead stand as a vowel repetition symbol in the following syllable. So e.g. instead of
: 3495 13 4 kno~
: 3509 38 6 ~w
it should be
: 3495 13 4 kno
: 3509 38 6 ~w
Also, please use fanart.tv covers/background whenever possible (especially when it seems that you even uploaded that cover to fanart.tv yourself).
