What an absolutely terrible scenario, millions of normalfags being exposed to blatantly plagiarized doujin music, not even aware of the original creator, while the thief is just some random teenager getting his already enormous ego-stoked by oblivious dick suckers all the while being paid for it. Making things worse is the publicity. If it had just been quietly swept under the rug and resolved before it got big it wouldn't have been a problem, but now it only serves to clue in similar vultures that there's a whole new range of music for them to rip off and claim their own - and I doubt these small doujin circles will want to bother with sorting out the legalities involved in this kind of thing.
