Eerie Halloween Song

Hello all!

Can anyone identify the song being played in this video at 4:09 to 4:23? I've heard it around the internet a couple times and I kind of like it, so I really wouldn't giving it a listen. Any help finding a song title would be greatly appreciated! YouTube link is below.

Thanks in advance!
