The majority of the songs are made by fans of the software, mostly amateurs but many are professional musicians and some became professional via Vocaloid usage.

There have, however, been a handful of official songs, but again, due to the nature of Vocaloid and its fandom... These were musicians hired to use the software.

When you consider there are over 40,000+ Miku original songs, its easy to understand how most end up like this. This is the story of how Vocaloid came big, however, and sadly how some 100 songs ended up also being the only ones out of the 40,000+ that were famous to be remembered... :-/
