One Hour Compo celebrates it's 400th round on Thursday June 9th at 9:00PM EST! Don't miss it!

Compo is a slang word for "composition competition" commonly used by the arrangement community. It is derrived from the demoscene competitions by the same name. Contrary to this, compos are less of a competition and more of an excerise in composition abilites. Each compo has it's own unique format and guidelines and while some are as short as 1 hour, others can last anywhere from a month, to a few months. It's important to remember that the primary purpose of compos are to hone your skills and abilites by working within, sometimes very constricting, guidelines. These techiniques have proven essential to the growth of countless musicians.

Remember: the only way to lose a compo, is to not participate.

Everything is fine in this anniversary round, the only restriction is that you must have worked on the song recently (during this round), it is not allowed to post a song you did years ago.

MIDI rips are allowed, but probably you won't win with a MIDI rip.

http://ocremix.org/community/topic/46700-prc364-the-14th-anniversary-free-round/

After uploading, please check if your song plays and can be downloaded and played without problems.
Only upload MP3 Files.

It is not necessary to use ThaSauce. You can upload the song anywhere you want, but I must have a download link. So if you use SoundCloud, don't forget to allow downloads, otherwise your song does not count as an entry or bonus mix. I will still use ThaSauce as a possible place to submit songs and upload all the songs to the ThaSauce page to have the songs at one central place.

If ThaSauce is down, please also submit the song somewhere else with a download link and post the link in the Ocremix Thread.

The winner may pick a source for PRC366 which is the second round from the new season next year.

"I checked through the MnP archives and didn't see this (rather quickly, so, sorry if I missed it!) The song I'd like to suggest is Freezeezy Peak from Banjo-Kazooie. It's one of the first video game themes I think of when I think of winter or Christmas. It's hard not to smile and be happy when you hear it!"
