Just the levels of influence that he draws from while creating something that sounds so uniquely him. Counting the time signatures is an exercise in frustration. The little production easter eggs hidden throughout are always fun to take note of. The metaphors and unique descriptions of certain events in Frank's life are fascinating. Plus his vocal style has matured so much in the last four years
Listen to it more. Literally everyone I know who likes this album, didn't like it the first couple times, myself included. Its a weirdly acquired taste. I remember when it first came out. I was listening to the tracks as people were uploading them on youtube, and telling my friends it sounded whatever.
Months later I'm listening to Siegfried while high as fuck, cocoon mode in bed. Mind was blown. Now its one of my favorite albums. I can listen to it start to finish any time. Every track is amazing. Do yourself a favor and give it more of a chance. It IS worth it. Probably my favorite album of all time not even gonna lie.
One of the most beautiful things about the album is the lack of structure. Its not a pop record. And honestly, all the best songs are in the middle and second half. Siegfried and White Ferrari are two of the best. Listen to the production and the layered vocals on Siegfried and tell me its not amazing. Even the short little tracks like Good Guy and Close To You are so sentimental and beautiful. So heartfelt. Self Control and Solo are just straight beautiful. Nikes, Ivy, Pink + White, and the other more popular tracks are good also, but those others I mentioned are really the meat of the album.
some of the songs really got to me. Specifically Helena, and Ariadna.
