Aphex Twin - Windowlicker. One of the most unique songs ever, period.
Alice In Chains - Rooster. Incredible story, beautiful composition, amazing vocals, possibly one of the greatest rock songs ever.
MF DOOM - Kon Queso. Sort of a deeper cut, but it’s definitely one of my favorite DOOM songs, I absolutely love the beat, lyricism, and sampling. Honestly the whole album I wish I could hear for the first time again.
