I randomly played this while practicing another song I'm writing. I'm afraid it might sound too much like something else, but I'm not sure. I mean I've never heard it before, but you never know, right?

The attachment is for Guitar Pro 5
I apologize if this is the wrong place for this thread.
Sounds vaguely familiar - but then again, what doesn't? Can't say that it reminds me of any particular song, so go ahead with it.
