To be fair, the beginning of Koshiro's composition also sounds like an intro that could have been borrowed from a baroque piece. Paging Desperado...
While we're at it, we could talk about the uncanny similarity of Actraiser's "Ending" to the 20th Century Fox fanfare.
Just to make it clear, I don't put Koshiro at fault for this. At times, don't you feel like you've come up with the greatest thing ever, only to find later you've unintentionally plagiarized it from some source that was in the back of your head?
