Can Anyone Identify This Song?

[dojima]

Hello.  Just came here on the off-chance that someone could help me to identify the song being played in the background of this stream.  I'm not sure if it's a Touhou related song or not.  It's very possible it isn't, but that's my best guess.  Hopefully someone knows the song whether it is or isn't Touhou related.
