Namesakes
One of the most remarkable things about the Risk of Rain soundtrack is the names of the songs.

Composer Chris Christodolou gave each one of them a name related to rain. Whether it’s in plain sight or a bit more elaborate.

Trivia

 * The 9th track, "Intermission", is literally an intermission with the words "End of part one" embedded in its frequency spectrum.
 * Other than Providence, all boss fight/teleporter event music is randomized from the following: Dew Point, Surface Tension, Moisture Deficit, Hailstorm, Double Fucking Rainbow, and Tropic of Cancer.
 * These are named musicBoss1a.ogg, musicBoss1b.ogg, musicBoss1c.ogg, musicBoss2a.ogg, musicBoss2b.ogg, and musicBoss2c.ogg respectively in the game files (with musicBoss3.ogg oddly also being Hailstorm).
