Perhaps this stretches the thematic content idea a little thin, but music label Ghostly International gives out free songs often enough that it's like Halloween there all the time. Just drop by their Website and chances are they'll have some forward-thinking electronic musical delight to sweeten your ears and make your life better.
Ghostly Essentials: Rarities Vol. 2 may have slipped past your senses. Rectify that as soon as you reach the end of this post, and in no time you'll be looking out the window at the changing leaves and graying skies while Locsil's cold, cosmic "Umbra" worms its ambient digital textures into your brain.
The Typing Monkey also digs the game of musical tag played between analog bleeps and something that sounds an awful lot like an acoustic guitar in "Between Rooms" by Myers Briggs. And the instrumental version of JDSY's "All Shapes" bounces with a flabby square-wave bass melody -- like The Great Pumpkin walking home all self-satisfied as the light of November 1st begins to bleach the sky.
Did we mention that it's free?
