Snowblind is a song from Silent Hill: Origins. It is track 20 in the game's soundtrack and was composed by Akira Yamaoka. It plays at Riverside Motel, after the cutscene where Travis Grady encounters Michael Kaufmann and Lisa Garland.
The song's title and role in the game is likely related to the 1972 song "Snowblind" by heavy metal band Black Sabbath, which is about cocaine addiction. A white, powdery drug (speculated to be PTV) is present in the room Michael and Lisa had occupied, and as revealed in Silent Hill, Lisa was addicted to the drug.
