Are there any methods that help one fall asleep faster?

The suggestion of listening to music works very well for some people, including myself. I'd reccomend being rather familiar with the song, so you aren't actively listening to it as much as you normally would be if you were just listening to music. There are some very great songs to fall asleep to, and here are some of the albums that I tend to use for falling asleep:

Radiohead - Kid A (first two tracks in particular)
Sigur Ros - ( ) works well, and Agaetis Byrjun and Takk... aren't bad
Brian Eno - Ambient 1: Music For Airports just like it sounds. Perfect.
Explosions in the Sky - The Earth Is Not A Cold Dead Place
Godspeed You! Black Emperor - F# A# oo

Sigur Ros tends to have me out within 10 minutes. Brian Eno often works faster.

Jam it back in, in the dark.
