the path is my favorite phemiec song. i get really emotional thinking about the alpha derse siblings. ugly story was a big part of the reason i got into homestuck though.
beyond that, karkalicous was a song i listened to for years & years before i got into homestuck because i thought it was entertaining. i need to listen to more homestuck parodys/fansongs.
theres some instrumental tracks i love, but i can't remember all of them off the top of my head though. one of them is land of pulse and haze by metianull.
