 that being said, you are one of my biggest inspirations. i can play several instruments, but i can't seem to go farther than cover some songs; i don't know where to start for original creations that i can be satisfied with. i've seen some in depth analysis of your music: https://www.hooktheory.com/theorytab/view/bill-wurtz/i-just-did-a-bad-thing https://www.youtube.com/watch?v=-0Bw2Rg5nFQ https://www.youtube.com/watch?v=1c15ecCCmbs and it seems like your music is very complicated. you've mentioned that every song for you is planned out in whole bef
 orehand,
  but for me, i can't seem to come up with anything that is melodic or harmonically satisfying to me. do you have any suggestions for me? appreciate it!
for someone in your situation, i can think of 2 things to suggest. 1, try using words some how. Music can escalate the power of words, immensely. and words can escalate the power of music, immensely. Sometimes without one or the other, things can be aimless. If you don't want to use words, then you could try using a picture. Music also can do just fine when it's being used to enhance a picture. Music and non-music are a match forged deep within the origins of the universe.
And the other thing i would recommend, specifically if you think you have a fine grasp on what notes and chords are gonna sound like, grab some staff paper and go to a room, a library is good because you have no access to an instrument, but i dunno if there's any real libraries nowadays, but just somewhere where you are sequestered with no access to instrument. just your mind, and paper. and a singular pitch reference is ok, but come on, you can remember your favorite songs well enough to snag an absolute pitch right? or maybe there's an elevator bell in the room that you can learn. Anyway, absolute is not even important here really. try to use words too. Write the lead sheet, with melody and chords, lyrics, the whole thing. As long as you are comfortable that you have the ability to know what it sounds like without using an instrument, which i suspect you do, the idea of writing a song entirely like that, just in your mind, and writing it down immediately on paper into finality, it can make you feel kinda powerful and also desperately insane, which is always good for writing
