User blog comment:The Ultimate Doomer/Music in Quake 2 "borrowed"?/@comment-1496755-20120311122107/@comment-4787559-20120312074337

Popular songs are often used for inspiration when composing, or video game music may be deliberately made to sound similar to songs by some band (as an homage or such). Completely ripping off a song (which I don't do), on the other hand, is a bit different. Still, it's kind of surprising how games such as DOOM got away with using entire melodies that were "borrowed" from other songs (but then again, Robert Prince was a lawyer...).
